Abstract
The first total synthesis of chaetocin ( 1), a potent histone methyltransferase inhibitor, is described in detail. Key reactions were radical bromination for α-oxidation of the diketopiperazine ring, and reductive radical coupling for construction of the dimeric core structure. Stereoselective construction of the disulfide bridges was achieved via substitution reaction with H 2S. The total synthesis of 1 was accomplished in nine steps starting from known d-amino acid derivatives. Total synthesis of non-natural ent-chaetocin ( ent- 1) was also achieved via the established synthetic route, starting from l-amino acid derivatives.
