A safe and scalable continuous flow strategy for Wolff-Kishner reductions that employs methanol as the solvent has been developed. The use of low-cost hydrazine as the reducing agent in combination with a caustic base provides an atom-efficient, environmentally friendly method for the deoxygenation of aldehydes and ketones to alkanes. Because of the required harsh and corrosive reaction conditions (200 degrees C, 50 bar), reactor materials such as stainless steel, glass, or any type of polymer have compatibility problems, rendering this process problematic on a production scale. The use of corrosion-resistant silicon carbide (SiC) as the reactor material opens up the possibility of performing Wolff-Kishner reductions on scale with a considerably improved safety profile. Methanol as the solvent significantly simplifies the workup procedure compared with the generally employed high-boiling solvents such as diethylene glycol. The continuous flow protocol was applied to a number of substrates and provided the desired products in good to high yields with space-time yields of up to 152 g L(-1)h(-1). In addition, a pharmaceutically valuable active pharmaceutical ingredient precursor was synthesized by employing this high-temperature/pressure Wolff-Kishner protocol.

Recovery of plastic waste is becoming crucial since the amount of such waste increases continuously. The objective of this study is to investigate the potential of the pyrolysis technique for the recovery of plastic waste. In that frame, the influence of temperature (550 degrees C or 600 degrees C) on the pyrolysis of pure polypropylene (PP), polyethylene (PE), polystyrene (PS) and polyethylene terephthalate (PET) was first studied. It is shown that whatever the type of polymer, aromatic compounds are mainly formed and could reach 55wt.-% of the oil fraction for PP and 31wt.-% for PE at 550 degrees C. In a second step, a PP/PE mixture and a model mixture representative of the packaging plastic waste stream were pyrolyzed to investigate the influence of a combination of polymers on the proportions and composition of the different fractions. The pyrolysis of the polymer mixtures shows that, even if the aromatic compounds formed are similar to those obtained for the virgin polymers, the proportion of aromatic compounds is much more important than when the polymers are pyrolyzed alone. Indeed, mixing PE with PP at a 50/50 ratio does not affect the amount of liquid, gas and solid fractions but leads to the formation of a higher quantity of xylene (39 wt-%) at 550 degrees C. The combination of the plastics in the model mixture has also led to a decrease of the amount of waxy compounds. Furthermore, it was shown that a higher amount of aromatics than expected was formed. As a conclusion, this study demonstrates that pyrolysis is an effective technique to recover plastic waste as aromatic compounds for the petroleum industry. In the specific conditions used in this study (proposed model mixture and pyrolysis conditions), it will favor the idea that sorting is not needed to recover plastic waste through pyrolysis since aromatics formation is favored when the stream is composed of a mixture of polymers.

The controllable phosphorylations of thioesters were developed. When the reaction was catalyzed by a palladium catalyst, aryl or alkenyl phosphoryl compounds were generated through decarbonylative coupling, while the benzyl phosphoryl compounds were produced through deoxygenative coupling when the reaction was carried out in the presence of only a base.

Methods for selective C-H bond functionalization have provided chemists with versatile and powerful toolboxes for synthesis, such as the late-stage modification of a lead compound without the need for lengthy de novo synthesis(1-5). Cleavage of an sp(3) C-H bond via hydrogen atom transfer (HAT) is particularly useful, given the large number of available HAT acceptors and the diversity of reaction pathways available to the resulting radical intermediate(6-17). Site-selectivity, however, remains a formidable challenge, especially among sp(3) C-H bonds with comparable properties. If the intermediate radical could be further trapped enantioselectively, this should enable highly site- and enantioselective functionalization of C-H bonds. Here we report a copper (Cu)-catalysed site- and enantioselective allylic C-H cyanation of complex alkenes, in which a Cu(ii)-bound nitrogen (N)-centred radical plays the key role in achieving precise site-specific HAT. This method is shown to be effective for a diverse collection of alkene-containing molecules, including sterically demanding structures and complex natural products and pharmaceuticals.

Through topology-guided synthesis, a Zr-based mesoporous MOF was successfully constructed, adopting a b-cristobalite-type structure. The MOF is embedded with well-arranged terpyridine coordination sites for facile post-syntheticmetalation, and can be effectively used as a general scaffold for the preparation of noble-metal-free catalysts. For instance, the scaffolded metal@MOF material exhibits highly efficient catalytic activity for alkene epoxidation and arene borylation.

Novel benzo[d] thiazole-based analogues were synthesized with the aim of screening their in vitro anticancer activity. All the new derivatives 4-21 were evaluated against human hepatocellular carcinoma (HepG-2) and breast cancer cells (MCF-7) using doxorubicin as a reference drug. All compounds exhibited excellent potency against MCF-7 (IC50 values ranging from 0.71 +/- 0.4 to 1.04 +/- 0.7 mu M) and variable promising potency against HepG-2 (IC50 ranged from 2.53 +/- 2.5 to 3.47 +/- 3.4 mu M) comparing with the standard (IC50 = 1.03 +/- 0.8 mu M and 2.85 +/- 1.9 mu M, respectively) in addition to their safety towards the normal cell line. Compounds 5, 6, 7, 13 and 16 having the highest cytotoxic activity, were further evaluated for their EGFR inhibitory activity using Erlotinib as a reference drug. Molecular docking studies were performed for the promising compounds 5, 6 and 7 to interpret their detected enzymatic activities based upon their binding interactions with the receptor. Moreover, cell cycle analysis and detection of apoptosis induction illustrated that compounds 5 and 6 exhibited a significant pre G(1) and G(2)/M cell cycle arrest, in comparison with the untreated MCF-7 cells. In addition, compounds 5 and 6 elevated the levels of the oncogenic parameters; Bax, p53 and caspase-3 with decreased level of Bcl-2. These previous encouraging results of biological evaluation of the newly synthesized benzothiazoles could recommend an excellent framework toward the detection of new potent antitumor leads.

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.
