Palladium-Catalyzed Allylic Substitution Reaction of Benzothiazolylacetamide with Allylic Alcohols in Water.

An efficient tetrakis(triphenylphosphine)palladium- and Brønsted acid catalyzed allylic substitution reaction of benzothiazolylacetamide with allylic alcohols in water has been developed, and the corresponding allylated products were afforded in good to excellent (up to 99%) yields with high regioselectivities. This straightforward protocol exhibits good functional group tolerance and scalability.
