Tetrahydro-β-carbolines, (S)-tetrahydroharman (8a) and (S)-1-phenyltetrahydro-β-carboline (8b), were asymmetrically synthesized starting from (R)-phenylglycinol and 1-benzyl-3-(2-bromoethyl)indole (1). Asymmetric synthesis of the 9-thio analogue (15) of 8a was also achieved.
以(R)-苯基甘氨醇和 1-苄基-3-(2-溴乙基)吲哚 (1) 为起点,不对称地合成了四氢-β-咔啉、(S)-四氢哈曼 (8a) 和(S)-1-苯基四氢-β-咔啉 (8b)。此外,还实现了 8a 的 9-硫代类似物 (15) 的不对称合成。
