Rapid and Effective Synthesis of α-Acyloxy-α-alkynyltrimethylsilanes
摘要:
alpha-Alkynyl-alpha'-trimethylsilylhydrazones are readily oxidized into diazo compounds under simple experimental conditions. These stable diazo species can in turn react with a range of carboxylic acids via a protonation-nucleophilic substitution sequence, leading to valuable alpha-acyloxy-alpha-alkynyltrimethylsilanes. This procedure avoids the delicate preparation and manipulation of alpha-hydroxypropargyltrimethylsilanes.
