A highly 1,1-regio- and enantioselective alkenylboration of undirected and unactivated alkenes has been developed, which allows chiral allylboronates to be efficiently synthesized from readily available terminal alkenes, alkenyl bromides and B2pin2. This method is distinguished by its use of an inexpensive chiral catalyst, readily available starting materials, mild and convenient reaction conditions
已经开发了一种高度 1,1-区域和对映选择性的无向和未活化烯烃的烯基硼化反应,它允许从容易获得的末端烯烃、烯基溴化物和 B 2 pin 2有效地合成手性烯丙基硼酸酯。该方法的特点是使用廉价的手性催化剂、容易获得的起始材料、温和方便的反应条件、可扩展性和实用性。
