β¦ Synopsis
A Formal Synthesis of (+)-Brefeldin A.
-An advanced synthetic intermediate for (+)-brefeldin A (IX) is efficiently synthesized from Weinreb amide (I). The procedure involves the highly stereoselective construction of the hydroxycyclopentane moiety via an oxabicycloheptanone unit. -(SUH,
