α-amino-vinylphosphine oxides by phosphinoenamination reaction between alkyl nitriles and phosphine oxides was developed. The combination of Mn(OAc)2 as a Lewis acid and guanidine as a Lewis base was found to be an efficient catalytic system for this reaction. A series of alkyl nitriles and phosphine oxides are compatible with this conversion, furnishing the desired products in up to 95% yield under mild conditions
开发了通过烷基腈和氧化膦之间的膦基胺化反应合成α-氨基-乙烯基氧化膦的方案。 Mn(OAc) 2作为路易斯酸和胍作为路易斯碱的组合被发现是该反应的有效催化体系。一系列烷基腈和氧化膦与该转化相容,在温和条件下以高达 95% 的产率提供所需的产物。此外,该方法展示了克级合成的能力。
