Abstract: Synthesis of some amide-ester linked 1,4-disubstituted 1,2,3-triazoles was carried out by employing copper(I)-catalyzed 1,3-dipolar cycloaddition of 2-azido-N-substituted acetamides and benzoic acid prop-2-ynyl esters. All the synthesized 28 1,4-disubstituted 1,2,3-triazoles are new. The synthesized triazoles were characterized by IR, 1H NMR, 13C NMR, HRMS and evaluated for their antimicrobial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Candida albicans, and Aspergillus niger. Compounds displaying potent antimicrobial activity against each of these microorganisms were found. Quantitative structure activity relationship studies for the synthesized compounds were also carried out to check the effect of various substituents in parent compound on antimicrobial activity.

A convenient synthesis of some new 1,4-disubstituted 1,2,3-bistriazoles (3a-3f, 4a-4f, 6a-6b, 7a-7b) is reported via copper(I)-catalyzed Huisgen 1,3-dipolar cycloaddition of various terminal alkynes with 1,4-bis(azidomethyl)benzene and 1,6-diazidohexane.

Annulation of benzoxy-tethered N-sulfonyl-1,2,3-triazoles and indoles has been developed in this paper, providing an efficient and convenient access to valuable cyclopenta[b]indoles in moderate to good yields. α,β-Unsaturated imine, which generated in situ from denitrogenation and 1,2-OBz migration of triazole, provided three carbons for the formal [3+2] cyclization reaction for the first time. (Figure presented.).

The metal-free catalyst tris(2,4,6-trifluorophenyl)borane has demonstrated its extensive applications in the 1,2-hydroboration of numerous unsaturated reagents, namely alkynes, aldehydes and imines, consisting of a wide array of electron-withdrawing and donating functionalities. A range of over 50 borylated products are reported, with many reactions proceeding with low catalyst loading under ambient conditions. These pinacol boronate esters, in the case of aldehydes and imines, can be readily hydrolyzed to leave the respective alcohol and amine, whereas alkynyl substrates result in vinyl boranes. This is of great synthetic use to the organic chemist.
