A decarboxylative allylic benzylation cocatalyzed by Pd/photoredox in a regio- and enantioselective manner has been achieved. Readily available aryl acetic acids are used as benzylic nucleophile equivalents without preactivation. This mild and atom-economical protocol expands the scope of coupling partners of allylic electrophiles. Vinyl epoxides could also go through this transformation smoothly,
已经实现了由 Pd/光氧化还原以区域选择性和对映选择性方式共催化的脱羧烯丙基苄基化。容易获得的芳基
乙酸用作苄基亲核试剂等效物,无需预活化。这种温和且原子经济的协议扩大了烯丙基亲电子试剂偶联伙伴的范围。
乙烯基环氧化物也可以顺利地进行这种转变,提供各种带有全碳四元立体中心的手性高
烯丙醇。
