  作者：Pakornwit Sarnpitak、Mikhail Krasavin

  DOI：10.1016/j.tet.2013.01.039

  日期：2013.3

  A conceptually new, two-step synthesis of medicinally important 1,2,4-triazoles from isocyanides and thiosemicarbazones was developed. The method is based on the recently discovered TMSCI-promoted reaction of isocyanides that yields rare N-1,N-3-disubstututed formamidrazones. (C) 2013 Elsevier Ltd. All rights reserved.
