A new approach to asymmetric synthesis of Stork's prostaglandin intermediate

Yasuharu Sakamoto; Takashi Takahashi; Katsuhiko Tomooka; Katsuya Ishikawa; Takeshi Nakai

Abstract A stereocontrolled approach to assymmetric synthesis of Storks prostaglandin intermediate 3 has been developed which involves the [2,3]-Wittig rearrangement and the Pd(II)-catalyzed allylic acetate rearrangement as the key steps.
