A visible-light photoredox catalyzed radical cascade cyclization of simple ethers with cyanamides is developed at room temperature. This strategy involves sequential inert C-sp3-H/C-sp2-H functionalizations through intermolecular addition reaction of oxyalkyl radicals to N-cyano groups followed by radical cyclization of iminyl radicals in situ generated with C-2 aryl rings. This method allows for efficient synthesis of tetracyclic benzo[4,5]imidazo[1,2-c]quinazolines. Importantly, this is the first example of an intermolecular-intramolecular radical cascade cyclization reaction of cyanamides.

Experimental solubilities have been determined by spectrophotometric methods for 1-chloro-4-bromobenzene, 1,4-dibromobenzene, 1,4-dichloro-2-nitrobenzene, benzoic acid, 4-nitrobenzoic acid, 3,5-dinitrobenzoic acid, 2-methoxybenzoic acid, 4-methoxybenzoic acid, 3-chlorobenzoic acid, 3,5-dinitro-2-methylbenzoic acid, 2-methylbenzoic acid, 3-methylbenzoic acid, 3,4-dichlorobenzoic acid, benzoin, 4-tert-butylbenzoic acid, 4-chlorobenzoic acid, 3,4-dimethoxybenzoic acid, 3,4,5-trimethoxybenzoic acid and o-acetoacetaniside dissolved in 2-ethyl-1-hexanol at 298.15 K. Our experimental measurements, combined with published solubility data retrieved from the published chemical and engineering literature, were used to derive Abraham model correlations for solute transfer into 2-ethyl-1-hexanol from both water and from the gas phase. The derived Abraham model correlations were found to back-calculate the measured experimental values to within +/- 0.12 log units (or less).

One of the key challenges to overcome multidrug resistance (MDR) in cancer is the development of more effective and general strategies to discover bioactive scaffolds. Inspired by natural products, we describe a strategy to achieve this goal by modular biomimetic synthesis of scaffolds of (Z)-allylic-supported macrolides. Herein, an Rh(III)-catalyzed native carboxylic acid-directed and solvent-free C-H activation allylation with high stereoselectivity and chemoselectivity is achieved. The generated poly-substituted allylic alcohol as a multifunctional and biomimetic building block is crucial for the synthesis of (Z)-allylic-supported macrolides. Moreover, the unique allylic-supported macrolides significantly potentiate the sensitivity of tumor cells to cytotoxic agents such as vinorelbine and doxetaxel by reversing p170-glycoprotein-mediated MDR. Our findings will inspire the evolution of synthetic chemistry and open avenues for expedient and diversified synthesis of bioactive macrocyclic molecules. One strategy to address multidrug resistance in cancer is the development of modular methods to access bioactive scaffolds. Here, the authors report a Rh(III)-catalyzed carboxylic acid-directed C(sp(2))-H allylation and apply it to the modular synthesis of (Z)-allylic macrolides which enhance antitumoral drug activity.

Utilizing a chiral bicyclic imidazole organocatalyst and adopting a continuous injection process, an alternative route has been developed for the efficient synthesis of chiral phthalidyl ester prodrugs via dynamic kinetic resolution of 3-hydroxyphthalides through enantioselective acylation (up to 99 % ee). The computational studies suggest a general base catalytic mechanism differing from the widely accepted nucleophilic catalytic mechanism. The structure analysis of the key transition states shows that the CH-pi interactions and not the previously considered cation/pi-pi interactions between the catalyst and substrate is the dominant factor giving rise to the observed stereocontrol.

A diverse range of ureas, N-acylureas, carbamates, and thiocarbamates has been synthesized in good to excellent yields by reacting N-acylbenzotriazoles individually with amines or amides or phenols or thiols in the presence of diphenylphosphoryl azide (DPPA) as a suitable azide donor in anhydrous toluene at 110 degrees C for 3-4 hours. In this route, DPPA was found to be a good alternative to trimethylsilyl azide and sodium azide for the azide donor in Curtius degradation. The high reaction yields, one-pot and metal-free conditions, straightforward nature, easy handling, use of readily available reagents, and in many cases avoidance of column chromatography are the notable features of the devised protocol.

O-Acylation of 1,3-dicarbonyl compounds provides enol esters which act as precursors for the synthesis of chiral alcohols, natural products, heterocycles and functional materials. Perfluoroalkanosulfonyl fluoride (RfSO(2)F) is a class of excellent hydroxyl-activating reagent, and has been extensively developed and used in the formation of C-F, C-O, C-N and C-S bonds in organic synthesis. In this work one-step O-acylation of 1,3-dicarbonyl compounds (1,3-diketones and beta-ketonic esters) with carboxylic acids activated by RfSO2F in alkaline media was disclosed, and the corresponding O-acylation products (enol esters) were generated in moderate to good yields. The optimized reaction conditions are as follows: 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as base, CH2Cl2 as solvent, n-C4F9SO2F as activating reagent, room temperature for 30 min and the molar ratio of n(1,3-dicarbonyls): n(RCOOH): n(RfSO2F): n(DBU) being 1.0 : 1.0 : 1.0 : 4.0. A novel reagent for one-step O-acylation of 1,3-dicarbonyl compounds with carboxylic acids was developed. The application of RfSO2F in organic synthesis was further expanded.

The work is focused on the design of drugs that prevent and treat Alzheimer’s disease (AD) and its complications. A series of 3-(4-aminophenyl)-coumarin derivatives designed, synthesised, fully characterised and evaluated in vitro/vivo. The biological assay experiments showed that some compounds displayed a clearly selective inhibition for acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). Among all compounds, compound 4m exhibited the highest AChE inhibition with an IC50 value of 0.091 +/- 0.011 mu M and compound 4k exhibited the highest BuChE inhibition with an IC50 value of 0.559 +/- 0.017 mu M. A zebrafish behaviour analyser (Zebrobox) was used to determine the behavioural effects of the active compound on the movement distance of the aluminium chloride-induced zebrafish. Compound 4m offered a potential drug design concept for the development of therapeutic or preventive agents for AD and its complications.

N-Aryl amides are an important class of compounds in pharmaceutical and agrochemical chemistry. Rapid and low-cost synthesis of N-aryl amides remains in high demand. Herein, we disclose an operationally simple process to access N-aryl amides directly from readily available nitroarenes and carboxylic acids as coupling substrates. This method involves the in situ activation of carboxylic acids to acyloxyphosphonium salt for one-pot amidation, without the need for isolation of the corresponding synthetic intermediates. Furthermore, the ease of preparation and workup allow the quick and efficient synthesis of a wide range of N-aryl amides, including several amide-based druglike and agrochemical molecules.

We present a computational study of polarizabilities and hyperpolarizabilities of organic molecules in aqueous solutions, focusing on solute-water interactions and the way they affect a molecule’s linear and non-linear electric response properties. We employ a polarizable quantum mechanics/molecular mechanics (QM/MM) computational model that treats the solute at the QM level while the solvent is treated classically using a force field that includes polarizable charges and dipoles, which dynamically respond to the solute’s quantum-mechanical electron density. Quantum confinement effects are also treated by means of a recently implemented method that endows solvent molecules with a parametric electron density, which exerts Pauli repulsion forces upon the solute. By applying the method to a set of aromatic molecules in solution we show that, for both polarizabilities and first hyperpolarizabilities, observed solution values are the result of a delicate balance between electrostatics, hydrogen-bonding, and non-electrostatic solute solvent interactions.
