The regioselectivity of the coupling of phenoxyallyllithium with allylic electrophiles was investigated. The allylation pattern corresponded with the hardness of the leaving group and the highest α-selectivity was observed in the reaction with allylic phosphate.
研究了苯氧基烯
丙基锂与烯丙基亲电体偶联的区域选择性。烯丙基化模式与离去基团的硬度相对应,在与烯丙基
磷酸酯的反应中观察到最高的 α 选择性。
