The benzylpyrrolidine amides 1a-1d, 3a-3e, 5a, and 5b were prepared from N-benzyl-L-proline methyl ester with corresponding diamines. Compounds 2a-2d, 4b, and 4e have similarly been synthesized from L-proline methyl ester and the corresponding diamines in refluxing methanol. In both cases, the reactions were accompanied by racemization. Prepared amides were transformed to salts, suitable for pharmacological testing (hydrogen maleates, hydrogen oxalates and hydrochlorides). The products were tested by selected methods of biochemical and behavioural pharmacology.
苯甲基吡咯啉酰胺1a-1d、3a-3e、5a和5b是由N-苯甲基-L-脯氨酸甲酯与相应的二胺制备而成。化合物2a-2d、4b和4e同样是由L-脯氨酸甲酯和相应的二胺在沸腾的甲醇中合成。在两种情况下,反应都伴随着外消旋反应。制备的酰胺被转化为适合进行药理学测试的盐(马来酸氢盐、草酸氢盐和盐酸盐)。这些产物通过生化和行为药理学的选定方法进行了测试。
