source. This reaction proceeds under mild reaction conditions without the use of a catalyst and an external oxidant. Various sorts of alkene substrates are transformed into the corresponding 1,2-dibrominated products in good to excellent yields with broad substrate scope and exclusive diastereoselectivity. This method offers a green and practical approach to synthesize vicinal dibromide compounds.
使用 1,3-二
溴-5,5-二甲基乙内酰
脲 (
DBDMH) 作为
溴源,实现了烯烃的直接 1,2-二
溴化方法。该反应在温和的反应条件下进行,无需使用催化剂和外部氧化剂。各种烯烃底物转化为相应的 1,2-二
溴化产物,产率从良好到优异,底物范围广,具有独特的非对映选择性。该方法为合成邻二
溴化物提供了一种绿色实用的方法。
