practical protocol for completely regioselective and highly stereoselective synthesis of vinyldiazaphosphonates from N-heterocyclic phosphine (NHP) and allenes via phospha-Michael/intramolecular nucleophilic substitution reaction has been developed. This transformation enabled the synthesis of valuable densely functionalized vinyldiazaphosphonates with a β-, γ-unsaturated ester moiety under mild reaction
已经开发了一种有效和实用的方案,用于通过膦-迈克尔/分子内亲核取代反应,从N-杂环膦(NHP)和丙二烯完全区域选择性和高度立体选择性地合成乙烯基二氮杂膦酸酯。该转化使得能够在温和的反应条件下合成具有β-,γ-不饱和酯部分的有价值的稠密官能化的乙烯基二氮杂膦酸酯。通过一系列合成操作证明了乙烯基二氮杂膦酸酯的合成效用。
