A rapid synthesis of 1,2,3,4-tetrahydro-7-hydroxyisoquinoline-3-carboxylic acid is given. Pictet-Spengler reaction on diiodo- or dibromo-substituted tyrosine (3-(3,5-dihalo-4-hydroxyphenyl)-2-aminopropanoic acid), followed by catalytic dehalogenation gives the desired compound in high optical purity.
给出了1,2,3,4-四氢-7-羟基异喹啉-3-羧酸的快速合成方法。在二碘或二溴取代的酪氨酸(3-(3,5-二卤-4-羟基苯基)-2-氨基丙酸)上进行 Pictet-Spengler 反应,然后催化脱卤,得到高光学纯度的所需化合物。
