[reaction: see text] A two-step approach that involves the synthesis of vinylsilane from allyl(isopropoxy)dimethylsilane (6) and the subsequent Pd-catalyzed cross-coupling of the resulting vinylsilane is applied in developing a novel diversity-oriented, three-component synthesis to homoallylic alcohols of common structure 1. Upon treatment of 6 with s-BuLi, the silylallylmetal 5 is generated and reacted with carbonyl compounds to produce functionalized vinylsilanes, which can couple with aryl/vinyl halides in the presence of palladium catalyst to afford 1.
[反应:见正文] 一种两步法被用于开发一种新颖的、面向多样性的、合成具有共同结构1的高烯丙醇的三组分合成方法。该方法包括由烯丙基(异丙氧基)二甲基硅烷(6)合成乙烯基硅烷,以及随后对所得乙烯基硅烷进行钯催化的交叉偶联。用仲丁基锂处理6时,会生成甲硅烷基烯丙基金属5,它与羰基化合物反应生成官能化的乙烯基硅烷,该乙烯基硅烷在钯催化剂存在下可与芳基/乙烯基卤化物偶联得到1。
