1,2,4-triazolo[1,5-a]pyridine-2-carboxylates are conveniently prepared from triazolopyridine-N-oxide precursors, by reacting sulfilimine and a nitrile oxide species. Herein, an efficient and straightforward procedure to prepare [1,2,4]triazolo[1,5-a]pyridine-2-carboxylate-N-oxide in continuous flow is reported. A mechanistic study performed using density functional theory (DFT) provided deep insights
1,2,4-三唑并[1,5-a]吡啶-2-羧酸盐可以通过硫亚胺和氧化腈物质反应,由三唑并吡啶-N-氧化物前体方便地制备。本文报道了一种在连续流中制备[1,2,4]三唑并[1,5-a]吡啶-2-羧酸酯-N-氧化物的有效且简单的程序。使用密度泛函理论 (DFT) 进行的机理研究提供了对整个反应流形的深入见解,并指示了如何减少副产物的产生。
