A concise total synthesis of (+)-curacin A, a potent antimitotic agent isolated from the cyanobacterium Lyngbya majuscula, is described. The synthesis features a new strategy to the 2-cyclopropyl-4-alkenyl substituted thiazoline unit in the natural product involving facile and selective thioacylation of the amino-alcohol 10 with the benzotriazole derived thioamide 11, leading to 28, as a key step. Cyclodehydration of 28 using Burgess' reagent then completed the synthesis of curacin A 1.

A total synthesis of (+)-curacin A 1 which features a facile and selective thioacylation of the polyene amino-alcohol 2 with the benzotriazole-derived cyclopropyl thioamide 3, leading to 15, as a key step is described.
作为关键步骤,描述了(+)-curacin A 1的全合成,其特征在于多烯氨基醇2容易地和选择性地被苯并三唑衍生的环丙基硫酰胺3进行硫代酰化,生成15。
