在钯催化剂的存在下,乙烯基苯并恶嗪酮与缺电子烯烃发生高度对映选择性的脱羧环加成反应。钯包括亲本苯并恶嗪酮在温和条件下的脱羧生成中间体,经过具有良好迈克尔受体的正式[4 + 2]环加成,生成具有优异的对映选择性、双立体选择性和对映选择性的高取代对苯二酚。
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.
