We describe the practical synthetic route for (2S)-7-methoxy-1,2,3,4-tetrahydro-2-naphthylamine 1(2S)-2-amino-7-methoxytetraline; (S)-AMT]. (2R)-2-(3-Methoxybenzyl)succinic acid [(R)-1] was obtained by the optical resolution of 2-(3-methoxybenzyl)succinic acid (1) as the salt of (1R,2S)-2-(benzylamino)cyclohexylmethanol (7), and (R)-1 was converted to the optically active (2S)-7-methoxy-1,2,3,4-te
我们描述了(2S)-7-甲氧基-1,2,3,4-四氢-2-萘胺1(2S)-2-氨基-7-甲氧基四氢萘的实用合成路线;(S)-AMT]。(2R)-2-(3-甲氧基苄基)琥珀酸[(R-1)]是通过光学拆分2-(3-甲氧基苄基)琥珀酸(1)作为(1R,2S)-2的盐而获得的。 -(苄氨基)环己基甲醇(7)和(R)-1被转化为旋光性(2S)-7-甲氧基-1,2,3,4-四氢-2-萘甲酸[[S)-2]通过分子内Friedel-Crafts反应,然后进行催化氢化。(S)-AMT不经消旋即通过霍夫曼重排从酸(S)-2获得。
