5-tetrahydro-1H-(1,4)diazepino(1,2-a) indoles (5a-f) and 1-(3-aminopropyl)-2-hydroxymethyl-3-phenylindoles (6a-f) are reported. The compounds (5a-f) were prepared by the lithium aluminum hydride (LAH) reduction of corresponding 11-phenyl-1H-1-oxo-2,3,4,5-tetrahydro(1,4)diazepino(1,2-a)indoles (4a-f). The precursors (4a-f) were, in turn, prepared by the catalytic reduction of 1-(2-cyanoethyl)-3-phenylindole-2-carboxylates
一系列新颖的11-苯基-2,3,4,5-四氢-1H-(1,4)二氮杂庚烷(1,2-a)吲哚(5a-f)和1-(3-氨基丙基)-2-报道了羟甲基-3-苯基吲哚(6a-f)。化合物(5a-f)是通过氢化铝锂(LAH)还原相应的11-苯基-1H-1-氧代-2,3,4,5-四氢(1,4)二氮杂庚烷(1,2- a)吲哚(4a-f)。依次通过催化还原1-(2-氰乙基)-3-苯基吲哚-2-羧酸酯(2a-f)并环化所得的1-(3-氨基丙基)制备前体(4a-f)。 -3-苯基吲哚-2-羧酸盐(3a-f)与氢化钠的二甲苯溶液。LAH还原2a-f仅产生预期的1-(3-氨基丙基)-2-羟甲基-3-苯基吲哚(6a-f),而不产生二氮杂庚并吲哚(5a-f)。已经针对标题化合物和中间体的抗5-羟基色胺(抗-5-HT)活性进行了筛选。
