Synthesis of a key intermediate for preparation of 4,5-didehydro prostaglandins containing an allenyl side-chain group via two-component coupling process. Synthesis of enprostil
Abstract
Enone 8, a key intermediate in the preparation of 4,5-didehydro prostaglandins via a two component coupling process, is prepared efficiently from readily available enone 6; the synthesis of enprostil, an antiulcer agent developed by Syntex, using enone 8 is also described.
