One-Pot, Three-Component Reaction Using Modified Julia Reagents: A Facile Synthesis of 4,5-Disubstituted 1,2,3-(NH)-Triazoles in a Wet Organic Solvent
摘要:
A new one-pot, three component reaction involving the use of Julia reagent, aldehyde, and sodium azide was developed for the efficient synthesis of N-unsubstituted 1,2,3-triazoles. This reaction could be carried out under mild reaction conditions without any precaution, and broad scope of substrates, both respect to Julia reagents and aldehydes, could be applied in this reaction system in generation of a small library of title compounds.

Zinc oxide-catalyzed solvent-freemechanochemical route has been developed for the rapid construction of C-S bond using a variety of thiols and phenacyl/benzyl/alkyl bromides via a nucleophilic substitution (SN2 mechanism). Notable advantages of this method include broad substrate scope, cleaner reaction profile, safe, scalable, high yields at ambient conditions and reuse of catalyst. Further, the

A series of new heterocyclic β-ketosulfides was prepared by the reaction of the corresponding heterocyclic thiols with α-bromoacetophenone and its derivatives. Oxidation of the products using m-CPBA gave the corresponding heterocyclic β-ketosulfones, which, on treatment with Selectfluor™ under anhydrous condition underwent electrophilic fluorination resulting in new heterocycles with difluoromethylene

respectively. A five-coordinated complex [NiLBr]PF6 (3) was further obtained by grinding NH4PF6 with complex 1 or 1′, or grinding KBr with complex 2. Complex 3 can also be obtained by direct grinding of complexes 1/1′ and 2. Complex 3 was subsequently used as a catalyst in the C–S bond cross-coupling of 2-bromoacetophenone and 2-mercaptobenzothiazole. The entire procedure from the synthesis to the catalytic

position of the ring, capable to interact through hydrogen bond with active site of the enzyme, is the contributing factor to the efficacy of the analog. Binding insight of the protein-ligand interaction of all the potent analogs was gained through molecular docking study. Furthermore, the drug likeness attributes of the potent derivatives were explored through ADME analysis.
