N-alkylations of secondary amines have been developed. By using DIAD and TPP (or PS-TPP) a variety of secondary amines can be converted to the corresponding tertiary amines in good to excellent yields with diverse alkylhalides; no formation of quaternary amine salts are observed. These protocols are amenable to combinatorial chemistry libraries, and are also useful for the syntheses of secondary amines by an
已经开发出可靠的仲胺的N-烷基化。通过使用DIAD和TPP(或PS-TPP),可以使用多种烷基卤将多种仲胺以高至极好的收率转化为相应的叔胺。没有观察到季胺盐的形成。这些方案适用于组合化学文库,也可用于通过可裂解的叔氨基树脂的酸裂解来合成仲胺。
