A simple and regiospecific synthesis of 4-alkoxy(amino)-2-trifluoromethyl pyrroles from 5-azido-4-alkoxy(amino)-1,1,1-trifluoro-pent-3-en-2-ones by an aza-Wittig cyclization of aminophosphoranes is described. The structures of the pyrroles and their synthetic intermediates were supported by NMR and HRMS analysis.
一种简单的区域特异性合成方法,由Aza-由5-叠氮基-4-烷氧基(氨基)-1,1,1-三氟戊-3-en-2-ones合成4-烷氧基(氨基)-2-三氟甲基吡咯描述了氨基膦的维蒂希环化。吡咯及其合成中间体的结构得到NMR和HRMS分析的支持。
