The reaction of (-)-(3,S)-6-hydroxy-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid (3a) with isocyanates and isothiocyanates gave the (+/-)-beta-carboline-hydantoin (4a-d) and -thiohydantoin systems (5a-d). The treatment of (-)-(1S,3S)-6-hydroxy-1-methyl-1,2,3,4-tetrahydro-beta-carboline-3-ca rbo xylic acid (3b) with isocyanates yielded the (+/-)-cis diastereomer of the beta-carboline-hydantoin
(-)-(3,S)-6-羟基-1,2,3,4-四氢-β-咔啉-3-羧酸(3a)与异氰酸酯和异硫氰酸酯的反应得到(+/-)- β-咔啉-乙内酰脲(4a-d)和-硫代乙内酰脲系统(5a-d)。用异氰酸酯处理(-)-(1S,3S)-6-羟基-1-甲基-1,2,3,4-四氢-β-咔啉-3-卡波酸(3b)得到(+ β-咔啉-乙内酰脲环(4e-h)的顺式非对映异构体。然而,3b与异硫氰酸酯的反应提供了相应的反式异构体(5e-h)。这些结果已通过13 C-NMR数据和核Overhauser效应(NOE)实验得到证实。测试了新化合物对中型苯并二氮杂receptor受体的体外结合亲和力。
