Enzyme-catalysed preparation of an .alpha.-substituted optically active carboxylic acid, using enantioselective hydrolysis of a mixture of the enantiomers of the corresponding amide, an Ochrobactrum anthropi or an Klebsiella sp. being used as the enzyme. During the hydrolysis both the L-carboxylic acid and the remaining D-carboxylic acid amide are obtained with high optical purity and high yield, while the activity of the micro-organism is high. A large number of .alpha.-substituted carboxylic acid amides with a remarkable structural variety can be hydrolysed in this manner.
evaluation (binding and functional) of the largest and most diverse collection of enantiopure SCRAs published to date. Our results revealed novel SCRAs that could be (or may currently be) used as illegal psychoactive substances. We also report, for the first time, the cannabimimetic data of 32 novel SCRAs containing an (R) configuration at the stereogenic center. The systematic pharmacological profiling
本发明提供了一种生产光学活性 L-或 D-叔亮氨酰胺的方法,这种方法易于操作,可在工业上进行。利用叔亮氨酰胺乙酸酯在 2-4 碳的低碳醇中的溶解度,DL 体的溶解度低,而 D 或 L 体的溶解度高,将 DL 体的乙酸酯沉淀在 2-4 碳的低碳醇中,将溶液中的叔亮氨酰胺转化为 D 或 L 体的叔亮氨酰胺。-溶液中的叔亮氨酰胺,以提高光学纯度。无。
