the synthesis of benzo[4,5]thiazolo[2,3- c ][1,2,4]triazoles and related heterocycles under mild conditions was herein developed. The key step of this transformation is an oxidative cyclization employing PhI(OAc) 2 as reagent. Scope and limitations (group functionality tolerance and sterics) were studied showing the robustness of the present methodology which can be used as potential access to new fused
本文开发了一种在温和条件下合成苯并[4,5]噻唑并[2,3-c][1,2,4]三唑和相关杂环的一锅两步反应。这种转化的关键步骤是使用 PhI(OAc) 2 作为试剂的氧化环化。研究了范围和限制(基团功能耐受性和空间),显示了本方法的稳健性,可用作获取新的融合杂环库的潜在途径。
