Chiral 2,2'-bis(diphenylarsino)-1,1'-binaphthyl (BINAs) was synthesized and found to be an effective ligand in an alkenyl iodide-using intramolecular asymmetric Heck reaction.

A catalytic asymmetric synthesis of halenaquinone (1) and halenaquinol (2) has been achieved using an asymmetric Heck reaction or a cascade Suzuki cross-coupling and an asymmetric Heck reaction as a key step. This synthesis also features the one-pot construction of a unique pentacyclic ring system from a tricyclic system using palladium chemistry. Moreover, the use of Ph3As as an achiral ligand has been found to enhance both the cascade Suzuki cross-coupling and also the Heck reaction to a synthetically useful extent.
