Brønsted acid catalyzed kinetic resolution of primary amines is described that is based on the condensation between an amine and a carbonyl compound. 1,3-Diketones react with racemic α-branched amines to furnish the corresponding enantioenriched enaminone and recovered starting material. Good to excellent enantioselectivity was observed with both aromatic and aliphatic primary amines. This process
描述了伯胺的布朗斯台德酸催化动力学拆分,其基于胺和羰基化合物之间的缩合。1,3-二酮与外消旋α-支化胺反应以提供相应的对映体富集的烯胺酮和回收的起始材料。对芳香族和脂肪族伯胺均观察到良好至极好的对映选择性。该过程代表了脂肪胺的第一个小分子催化动力学拆分。
