(3-Bromoalken-1-yl)dialkylboranes, generated by hydroboration of propargyl bromide with dialkylboranes, smoothly rearranges to (E)-allylic boranes which can be trapped with aldehydes. The resulting one-pot three-component sequence represents a route to anti-homoallylic alcohols in fairly good yields. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
(3-溴丙烯-1-基)二烷基硼烷由炔丙基溴化物与二烷基硼烷发生水合反应生成,随后会顺利重排为(E)-烯丙基硼烷,这些产物可以被甲醛等醛类化合物捕获。所得到的三组分一锅反应代表了一条合成反式 Homoalllylic 酒精的路线,产率相当不错。 (C) 1998 由 Elsevier Science Ltd. 出版。所有权利保留。
