A Simple One‐pot Three‐component Synthesis of Dihydrobenzo[4,5]imidazo[2,1‐
<i>b</i>
]thiazol‐3‐ols by Reaction of Acyl Chlorides, Isocyanides, and 2‐Mercaptobenzimidazoles
The reactive imidoyl chloride adducts generated in situ from the reaction of isocyanide and acyl chlorides were trapped by 2‐mercaptobenzimidazole to yield highly functionalized dihydrobenzo[4,5]imidazo[2,1‐b]thiazoles in excellent yields.
由异氰化物和酰氯反应原位生成的反应性亚氨酰氯加合物被2-巯基苯并咪唑捕获,以高收率得到高度官能化的二氢苯并[4,5]咪唑并[2,1- b ]噻唑。
