Intramolecular Heck Reaction

The thiaestrane 7 was synthesized by two sequential Heck reactions starting from the thiophene derivatives 8a–8c, which contain a (Z)-halogenovinyl group, and the enantiopure hydrindene 2a. The first intermolecular Pd-catalyzed reaction leads to 11a and 11b in a highly regio- and diastereoselective manner. A subsequent intramolecular Heck reaction catalyzed by the palladacycle 4 then gave the thiasteroid 7 with an unusual cis-junction of the rings B and C.

Intramolecular Heck Reaction

The first total synthesis of S-(+)-XJP and R-(−)-XJP has been achieved via intramolecular Heck reaction. A latent functionality strategy was implemented to circumvent the racemization in this endeavor.
