Synthetic studies on palmarumycin C-6 with a naphthyl acetal at the C-3 position in 4,7-dihydroxy-1-indanone as a lower homologue of spirobisnaphthalenes are described herein. We investigated three approaches: 1) Nazarov cyclization of benzoylketene acetal, 2) intramolecular Friedel-Crafts acylation of naphtho[1,8-de]-1,3-dioxin-2-aryl-2-acetic acid chloride, and 3) double oxa-Michael addition of 1,8-dihydroxynaphthalene to 3-bromo-l-indenone. The last approach successfully afforded the natural product after the removal of acetates that serve as protecting groups for phenolic hydroxyls under acidic conditions.

Benzotriazoles (4-6) were synthesized which were further reacted with different substituted benzoic acids and phenacyl bromides to synthesize benzotriazole derivatives (7-40). The synthetic compounds (7-40) were characterized via different spectroscopic techniques including EI-MS, HREI-MS, H-1-, and C-13 NMR. These molecules were examined for their anti-hyperglycemic potential hence were evaluated for alpha-glucosidase and alpha-amylase inhibitory activities. All benzotriazoles displayed moderate to good inhibitory activity in the range of IC50 values of 2.00-5.6 and 2.04-5.72 mu M against alpha-glucosidase and alpha-amylase enzymes, respectively. The synthetic compounds were divided into two categories A and B, in order to understand the structure-activity relationship. Compounds 25 (IC50 = 2.41 +/- 131 mu M), (IC50 = 2.5 +/- 1.21 mu M), 36 (IC50= 2.12 +/- 1.35 M), (IC50 = 2.21 +/- 1.08 mu M), and 37 (IC50 = 2.00 +/- 1.22 mu M), (IC50 = 2.04 +/- 1.4 mu M) with chloro substitution/s at aryl ring were found to be most active against alpha-glucosidase and alpha-amylase enzymes. Molecular docking studies on all compounds were performed which revealed that chloro substitutions are playing a pivotal role in the binding interactions. The enzyme inhibition mode was also studied and the kinetic studies revealed that the synthetic molecules have shown competitive mode of inhibition against alpha-amylase and non-competitive mode of inhibition against alpha-glucosidase enzyme.

A simple, facile and efficient method has been developed for the Friedel-Crafts benzoylation of arenes using magnetic gamma-Fe2O3 nanoparticles under solvent-free sonication. The gamma-Fe2O3 nanoparticles were used as an efficient and magnetically recoverable catalyst for the synthesis of aromatic ketones in good to excellent yields at room temperature under solvent-free. The reaction occurred with high regioselectivity under mild condition. The magnetic gamma-Fe2O3 nanoparticles are economically synthesized in large-scale, easily separated from the reaction mixture by an external magnet and able to be reused several times without significant loss of the catalytic performance, which make them easy application to industrial processes.

Friedel-Crafts (FC) acylation reactions were exploited in the preparation of ketone-functionalized aromatics. Environmentally more friendly, solvent-free mechanochemical reaction conditions of this industrially important reaction were developed. Reaction parameters such as FC catalyst, time, ratio of reagents and milling support were studied to establish the optimal reaction conditions. The scope of the reaction was explored by employment of different aromatic hydrocarbons in conjunction with anhydrides and acylation reagents. It was shown that certain FC-reactive aromatics could be effectively functionalized by FC acylations carried out under ball-milling conditions without the presence of a solvent. The reaction mechanism was studied by in situ Raman and ex situ IR spectroscopy.

Polyfunctional arenes are an important part of the chemical value chain. To improve the efficiency of their synthesis, we have investigated a multicomponent approach built upon the Catellani platform. Here, we describe a 4-component coupling of aryl iodides lacking an ortho substituent that installs 3 discrete functional groups on the arene in a single step. The process is regio- and chemoselective and uncovers remote substituent effects that have a pronounced influence over inter mediate Pd-(II) complexes. These intermediates have been a long-standing focus of the Catellani-reaction development, but persistent challenges have given rise to the well-known ortho effect. We now show that the ortho effect can be a positive element of reaction design, and that previously problematic iodides can now be used in complexity-generating transformations. In expanding the scope of the Catellani platform, we hope to provide mechanistic considerations to guide future reaction design, while also improving the environmental footprint of synthesizing polyfunctional arenes.

We report the practical synthesis of a key fragment of islatravir (MK-8591), a novel nucleoside reverse transcriptase translocation inhibitor (NRTTI) currently under investigation for treatment and pre-exposure prophylaxis (PrEP) against HIV infection. The fragment, the unnatural nucleobase 2-fluoroadenine, is incorporated into MK-8591 via a biocatalytic aldolglycosylation cascade, which imposes stringent requirements for its synthesis and isolation. Presented herein is the development work leading to a practical, scalable route from guanine, featuring a dual fluorination approach to a novel 9-THP-2,6-difluoropurine intermediate that enables a mild, highly selective, direct amination. This one-pot fluorination/amination sequence utilizes a direct isolation to deliver high purity 9-THP-2-fluoroadenine, which features ideal properties with respect to reactivity, solubility, and crystallinity. An acid-catalyzed liberation of 2-fluoroadenine in aqueous buffer delivers the appropriate purity profile to facilitate the enzymatic cascade to access MK-8591.

A multi-gram-scale synthetic route to a novel, bifunctional normorphan 3D building block bearing orthogonally reactive vinyl MIDA boronate and N-2,4-dimethoxybenzyl (DMB) amide functional handles has been developed. Synthetic manipulation at each of the functional handles has been demonstrated including Suzuki-Miyaura cross-coupling, exo-diastereoselective hydrogenation, N-DMB group removal and lactam reduction. Normorphan cores derived from the building block satisfied AstraZeneca’s ‘rule of 2’ for building blocks and had a high fraction of sp(3) hybridised carbon atoms (Fsp(3)). A virtual lead-like library of 344 compounds derived from the building block had attractive lead-like properties. The 3D building block has been commercialised by Redbrick Molecular and is currently available for purchase. (C) 2021 Elsevier Ltd. All rights reserved.

Green synthesis of pyrazolo[3,4-b]quinolinones was designed using bioproduct pyridine-2-carboxylic acid (P2CA) as a green and efficient catalyst. The multi-component reaction of aldehydes, 1,3-cyclodiones and 5-amino-1-phenyl-pyrazoles regioselectively produced pyrazolo[3,4-b]quinolinones in excellent yield (84-98%). Recyclization of the catalyst was also investigated. The electronic effect of the various substituents in aromatic rings indicated that the reaction proceeded through the carbocation intermediate. This newly designed protocol very quickly constructed products conventionally under milder conditions.

Endeavor to discover biorational natural products-based insecticides, two series (30) of novel (9S)-acyloxy derivatives of quinidine and dihydroquinidine were prepared and assessed for their insecticidal activity against Mythimna separata in vivo by the leaf-dipping method at 1 mg/mL. Among all the compounds, especially four derivatives exhibited the best insecticidal activity with final mortality rates of 71.4 %, 75.0 %, 71.4 %, and 75.0 %, respectively. Relatively speaking, 9-hydroxy group is well tolerated, and the results showed that after modification of the hydroxy group with an acyloxy group, the insecticidal activity was significantly increased; the configuration at C8/9 position is important for insecticidal activity, and the (9S)-configuration is optimal; modification of the out-ring double bond is acceptable, and hydrogenation of the double bond enhances insecticidal activity. These preliminary results will pave the way for further modification of quinidine in the development of potential new insecticides.

Nickel-catalyzed reduction of (het)arenecarboxylic acids with hydrosilanes in the presence of dimethyl dicarbonate as the activator affords the corresponding aldehydes. The role of the activator is the conversion of the acids into their anhydrides undergoing C?O cleavage. The good yields were achieved in case of substrates bearing electron-donating and electron-neutral groups.
