Heterogeneous organocatalysts hold great potential as they offer practical advantages in terms of purification and reusability compared with the homogeneous counterpart. A puzzling aspect is the solvent effect on their catalytic performance. Here we propo

We have developed a convenient development-scale reactor (0.44 mol/h) to prepare diazomethane from N-methyl-N-nitroso-p-toluenesulfonamide (MNTS) in ~80% yield. Diazomethane (CH2N2) made with this reactor is extracted into nitrogen gas from the liquid reaction mixture, effectively removing it from reagents and byproducts that may interfere in subsequent reactions. Vertically oriented tubular reactors were used to produce and consume diazomethane in situ. Key features of this reactor include high productivity and correspondingly low reactor volume (reactor volume/liquid flow rate = 6.5 min) and a commercially available gas/liquid separator equipped with a selectively permeating hydrophilic membrane. The design of the reactor keeps the inventory below 53 mg of CH2N2 during normal operation. The reactor was demonstrated by generating CH2N2 that was used in a connected continuous reactor. We evaluated esterification reactions and a continuous Pd-catalyzed cyclopropanation reaction with the reactor and achieved high conversion with 1.5 and 4.1 equiv of MNTS precursor, respectively.

On the basis of rational drug design fourteen novel compounds having benzoic acid as acidic head,?hydrazone?as?linker?and?substituted?diaryl?sulfanyl/aryl-cyclohexylsulfanyl?as?a?hydrophobic?tail?were synthesized?and?characterized by physicochemical and spectrophotometric (FTIR, Mass, 1HNMR and 13CNMR) analysis. The spectral data were satisfactory with their structures. The?designed compounds were docked against peroxisome proliferated activated receptors (PPARγ) and further evaluated for in vitro PPARγ agonist activity and in vivo hypoglycemic activity in wistar strain of albino rats.?Compound 3k and 3m exhibited potent?anti-diabetic activity without ulcerogenic toxicity and minimum side effects as weight gain. Therefore these compounds would be considered as promising agents for the development of novel antidiabetic agents.
