An Efficient Microwave Assisted Synthesis and Antimicrobial Activty of 1,2,3-Triazolyl-pyrrolidinyl-quinolinolines
摘要:
A novel series of 1,2,3-triazolyl-pyrrolidinyl-quinolinolines are synthesised by the Click reaction of alkynes with aromatic azides catalysed by CuI under microwave assisted and conventional conditions. All synthesized 1,2,3-triazoles are screened for their in vitro antimicrobial activity against different bacterial and fungal pathogens. Majority of the synthesized compounds demonstrate moderate to good inhibition zones compared to the standard drugs.

Synthesis of some novel classes of quinolizine-, indolizine- and pyrido-1,4-oxazine-fused quinoline derivatives via a three-component reaction under solvent-free conditions by exploring the 'tertiaryamine effect' reaction strategy.
An unprecedented cascade dearomative cyclization through hydrogen-bonding-assisted hydride transfer is realized. The aggregate effect of HFIP enables the rapid buildup of polycyclic amines directly from phenols and o-aminobenzaldehydes via a cascade dearomatization/rearomatization/dearomatization sequence. This unique transformation addressed the drawbacks of hydride transfer-involved redox-neutral
Carbocation-initiated cascade [1,5]-hydride transfer/cyclization and dimerization reactions were developed to synthesize dihydrodibenzo[b,e]azepine and octahydrodipyrroloquinoline derivatives in high yields. These redox-neutral C(sp3)–H functionalization-involving cascade reactions feature transition-metal-free, high atom- and step-economy, and environmental friendliness with water as the sole byproduct
