One-pot eschenmoser episulfide contractions in DMSO: Applications to the synthesis of fuligocandins A and B and a number of vinylogous amides

Pettersson, Birgitta,Hasimbegovic, Vedran,Bergman, Jan

, p. 1554 - 1561 (2011/05/19)

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 DMSO proved to be an efficient and general method for the synthesis of a variety of vinylogous amides, such as azepan-2- ylidenepropan-2-one. 2011 American Chemical Society.
