Functionalized phosphonium salts in Wittig reactions give ethylenic amines. With aldehydes the nature of the carbon chain and of the substituents on nitrogen have no influence on stereochemistry; ethylenic ketones, give aminopolyenes. Steroids give aminosteroids if a large excess of phosphonium salt is used. Amphiphilic compounds may therefore be prepared and aminoalkyl groups may be introduced to
Wittig反应中的官能化phospho盐会生成烯胺。对于醛,碳链的性质和氮上的取代基的性质对立体化学没有影响。乙烯酮,生成氨基多烯。如果使用大量过量的salt盐,类固醇会产生氨基类固醇。因此可以制备两亲化合物,并且可以将氨基烷基引入具有潜在生物活性的分子中。
