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.
