phosphinoylacetic acids derived from P(O)–H compounds were used as the starting materials in the reaction, providing a highly stereoselective and efficient method for constructing α,β-unsaturated phosphine oxides. Moreover, this simple and practical procedure provides an alternative and more environmentally friendly synthesis strategy for this type of P-functionalized alkenyl compounds.
各种各样的可商购的醛已被用于Knoevenagel缩合反应,以得到E-烯基氧化膦和乙烯基氧化膦。衍生自P(O)–H化合物的随时可用的膦酰基乙酸用作反应的起始原料,为构建α,β-不饱和氧化膦提供了高度立体选择性和有效的方法。而且,这种简单而实用的方法为此类P-官能化的烯基化合物提供了另一种更环保的合成策略。
