Reaction of activated 2,2-dimethylaziridines with Grignard reagents RMgHal in boiling THF can yield the products of normal aziridine ring opening, the rearranged opening products , and the methallylamides (isomers of ). The product distribution depends on R, Hal, and experimental conditions, and very strongly on the nature of the activating group A. It is shown that is opened (reversibly for A = sulfonyl)
活化的2,2-二甲基氮丙啶与Grignard试剂RMgHal在沸腾的THF中反应,可以生成正常氮丙啶开环的产物,重排的开环产物和甲基烯丙酰胺(的异构体)。产物分布取决于R,哈尔和实验条件,和非常强烈的活化基团A.结果表明的性质被打开(可逆地为A =磺酰基)形成通过Hal的路易斯酸辅助攻击θ在的叔碳(被Hal异常开口θ)。证据表明,以及来自该中间体。
