Palladium-Catalyzed Hydrofunctionalization of Vinyl Phenol Derivatives with Heteroaromatics
摘要:
A hydroheteroarylation reaction of vinyl phenols using an alkyl chloride as the sacrificial hydride source is reported. The method tolerates a wide range of heterocycles as the exogenous nucleophile including indoles and pyrroles. The resulting products are easily processed to biologically relevant scaffolds.

A mild, regiospecific Brønstedacid-catalyzed hydroarylation of activated olefins, capable of the formation of quinone methide-like intermediates, has been investigated. Variously substituted 2- and 4-vinylphenols, 4-vinylaniline or 6-vinyl-naphthalen-2-ol were successfully implemented in a sequential protonation and Friedel–Crafts-type alkylation reaction of electron-rich arenes.
