  One-Pot Eschenmoser Episulfide Contractions in DMSO: Applications to the Synthesis of Fuligocandins A and B and a Number of Vinylogous Amides

  摘要：

  Practical total syntheses of the natural products fuligocandin A (2a) and fuligocandin B (3) have been achieved through a convergent strategy depending on the Eschenmoser episulfide contraction as a key step. Conducting the reaction in DAIS proved to be an efficient and general method for the synthesis of a variety of vinylogous amides, such as azepan-2-ylidenepropan-2-one.
