Synthesis of the N-acetylcysteamine thioester of seco-proansamitocin

(Chemical Equation Presented) The enantioselective total synthesis of the N-acetylcysteamine thioester of seco-proansamitocin, a key biosynthetic intermediate of the highly potent antitumor agent ansamitocin, is described, which twice utilizes the Nagao a
