The kinetic resolution of racemic heterocyclic amines via acylation with N-tosyl-(S)-prolyl chloride was systematically investigated. It was established that racemic mixtures of aromatic amines could be resolved with high efficiency, while the acylation of 2- and 3-methylpiperidines occurred with low diastereoselectivity. A method for the preparation of enantiomerically pure (3R)-7,8-difluoro-3-methyl-3
系统研究了外消旋杂环胺经N-甲苯磺酰基-(S)-脯氨酰氯酰化的动力学拆分。已经确定,芳族胺的外消旋混合物可以高效分离,而2-和3-甲基哌啶的酰化则以低的非对映选择性发生。开发了制备对映体纯的(3 R)-7,8-二氟-3-甲基-3,4-二氢-2 H- [1,4]苯并恶嗪的方法。
