, p. 458 - 469 (2018)
This paper elicits the synthesis of twenty five 1,4-disubstituted 1,2,3-triazole analogs (5a–5y) comprising thioether and ester linkages from aryl(prop-2-yn-1-yl)sulfanes and benzyl 2-azidoacetates employing Cu(I) catalyzed Huisgen 1,3-dipolar cycloaddition. Structures of synthesized compounds were elucidated by spectroscopic techniques like FTIR, 1H NMR, 13C NMR, and HRMS. Newly synthesized compounds were screened for in vitro antimalarial evaluation against P. falciparum strain and microbicidal potential against B. subtilis, S. epidermidis, E. coli, P. aeruginosa, C. albicans, and A. niger. Some of synthesized triazoles displayed moderate antimalarial activity against tested strain, while, the compounds 5i and 5n were found to exhibit significant inhibitory activity against most of the tested microbial strains.

A chiral phosphoric acid-catalyzed asymmetric Mannich-type reaction of α-diazo esters with in situ generated N-acyl ketimines, derived from 3-hydroxyisoindolinones has been demonstrated in this communication. A variety of isoindolinone-based α-amino diazo esters bearing a quaternary stereogenic center were afforded in high yields (up to 99%) with excellent enantioselectivities (up to 99% ee). Furthermore, the synthetic utility of the products has been depicted by the hydrogenation of the diazo moiety of adducts.

A novel generation of oxazole ylide and interception with sulfonamide have been well developed to construct fully substituted amidines. This copper-catalyzed four-component reaction incorporates two diazo molecules to target amidines and shows broad substrate scope, excellent functional groups tolerance and good to excellent yields.
