The catecholamine analogs (±)-1-(3,4-dimethoxyphenyl)-2-alanine (1), β-(3,4-dimethoxyphenyl)ethylamine (2), (±)-1-(3,4-dimethoxyphenyl)-2-amino propane (3), (±)-erythro, threo-α-aminomethyl-3,4-dimethoxybenzyl alcohol (4), and (±)-erythro, threo-α-methylaminomethyl-3,4-dimethoxybenzyl alcohol (5) have been synthesized and optimized yields are reported. The availability of certain carbon-14 compounds has dictated logical starting points in the synthesis of 14C-tagged analogs. These syntheses were designed for metabolic and disposition work in connection with a pilot project concerned with the aetiology of schizophrenia with particular reference to the Osmond–Smythies – Harley-Mason hypothesis (2) of 1952.
儿茶酚胺类似物(±)-1-(3,4-二甲氧基苯基)-2-丙氨酸(1)、β-(3,4-二甲氧基苯基)乙胺(2)、(±)-1-(3,4-二甲氧基苯基)-2-氨基丙烷(3)、(±)-erythro,threo-α-氨甲基-3,4-二甲氧基苄醇(4)和(±)-erythro,threo-α-甲基氨甲基-3,4-二甲氧基苄醇(5)已合成,并报道了优化产率。某些碳-14化合物的可获得性决定了合成14C标记类似物的合理起点。这些合成是为了在与关于精神分裂症病因学有关的试点项目中进行代谢和处置工作而设计的,特别是参考了1952年Osmond–Smythies – Harley-Mason假设(2)。
