Abstract

An efficient procedure was developed for the synthesis of 1-[(triisopropylsilyl)ethynyl]-1λ3,2-benziodoxol-3(1H)-one on a 100-mmol (36-g) scale. The benziodoxolone can be used for the gold-catalyzed direct alkynylation of indole, 2-hexylthiophene, or N,N-dibenzylaniline on a 5- to 10-mmol scale.

摘要

有效的过程是为1的合成开发- [(三异丙基硅烷基)乙炔基]-1λ 3,2-苯碘酰-3(1 ħ) -酮上的100毫摩尔(36克)的规模。苯并恶唑酮可用于金催化的吲哚,2-己基噻吩或NN-二苄基苯胺的5至10 mmol规模的直接炔基化反应。
