reductive monoalkyl- ation of amines and amine derivatives with aldehydes is reported. Treatment of aldehydes with primary amines, secondary amines, O- trimethylsilylhydroxylamine, and N,N-dimethylhydrazine in lithi- um perchlorate/diethyl ether and trimethylsilyl chloride, followed by BH3·NEt3 reduction, and straightforward workup afforded sec- ondary amines, tertiary amines, N-substituted hydroxylamines
报道了一种用醛还原单烷基化胺和胺衍生物的有效通用程序。在高氯酸锂/乙醚和三甲基氯硅烷中用伯胺、仲胺、O-三甲基甲硅烷基羟胺和 N,N-二甲基肼处理醛,然后进行 BH3·NEt3 还原,直接后处理得到仲胺、叔胺,N-取代的羟胺和肼,分别。α-氨基酯与醛的还原烷基化选择性地提供相应的N-单烷基化α-氨基酯。
