HDAC inhibitor Spiruchostatin A was synthesized via a route that differs significantly from previously reported routes. The key step involves a latent thioester that initiates a chemoselective transformation similar to native chemical ligation to form the macrocyclic alanine−cysteine amide bond. The easily prepared latent thioester—the first such moiety reported in enantiomerically pure form—is designed
