ChemInform Abstract: Recent Progress on the Studies of the True Catalyst in the Heck Reaction with Supported Pd Particles

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.

Supported Pd

Graphene-supported Palladium composites were prepared through irradiation of the mixture of K2C2O4, Pd and graphene oxide (GO) with UV light in the presence of ethylene glycol (EG). Since the two-dimensional sheet of GO has a huge surface area, the as-synthesized graphene supported Pd composites kept excellent catalytic activity. There is no reduction agents that were used in the process of synthesis of graphene supported Pd composites. The good yield of cinnamic acid could be obtained when using the as-synthesized graphene-supported Pd composites as a catalyst in the reaction of iodobenzene, acrylic acid and triethylamine in the water system. Furthermore, no obvious mass loss of catalyst could be observed when being used to catalyze the heck reaction multiple times.
