Vinyl benzoxazinanones undergo highly enantioselective decarboxylative cycloadditons with electron-deficient olefins in the presence of palladium catalyst. Palladium includes the decarboxylation of the parent benzoxazinanones under mild conditions to produce an intermediates undergo a formal [4 + 2] cycloadditon with good Michael acceptors to produce highly substituted hydroquinolines with excellent reio-, distereo-, and enantioselectives.
