We report a novel catalyst Pd/SOS that catalyzes the dual C–C bond forming coupling of an iodoarene moiety with an internal alkene and an external alkyne via an intramolecular Heck reaction, followed by an intermolecular Sonogashira reaction, respectively.

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.

Intramolecular Heck Reaction

Our recent progress on the total synthesis of marine anti-cancer sesquiterpene quinone/hydroquinone dysideanone B and dysiherbol A was briefly highlighted. This success relied on some key transformations. The union of the terpene and quinone/hydroquinone moieties was realized through a site and stereoselective α-position alkylation of Wieland–Miescher ketone derivative with a bulky benzyl bromide. The 6/6/6/6-tetracycle of dysideanone B was constructed using an intramolecular radical cyclization and the 6/6/5/6-fused core structure of dysiherbol A was forged by an intramolecular Heck reaction, respectively. The possible origin of ethoxy group in dysideanone B was revealed by mimicking the isolation conditions at a late-stage. The structure of dysiherbol A was revised through the total synthesis of this natural product. Schmalz’s synthesis of dysiherbol A was also included.
