Abstract The carbon–carbon double bond formation via neodymium-mediated Barbier-type reaction of ketones and allyl halides in the presence of diethyl phosphite is reported for the first time. The reaction is highly α-regioselective and was conveniently carried out under mild conditions in a one-pot fashion. From a synthetic point of view, a series of conjugated alkenes were obtained in moderate to
摘要 首次报道了在亚磷酸二乙酯存在下,通过钕介导的酮和烯丙基卤化物的Barbier型反应形成碳-碳双键。该反应是高度α-区域选择性的,并且在温和条件下以一锅法方便地进行。从合成的观点来看,在可行的反应条件下,在该一锅法反应中,以中等至良好的产率获得了一系列共轭烯烃。
