A highly practical method for the enantioselective allylation of ketone-derived benzoylhydrazones has been developed. The previously reported strained silacycle reagent 1 reacts with a wide variety of benzoylhydrazones to give the hydrazide products with good to excellent enantioselectivity (84-97% ee). A mechanism in which the acylhydrazone becomes caovalently attached to the silane has been established
已经开发了一种用于酮衍生的苯甲酰腙的对映选择性烯丙基化的非常实用的方法。先前报道的应变硅环试剂 1 与多种苯甲酰腙反应,得到具有良好至优异对映选择性 (84-97% ee) 的酰肼产物。已经建立了酰基腙与硅烷共价连接的机制。
