Certain trans-2,3,4,4a,5,9b-hexahydro-1H-pyrido-[4,3-b]indoles are useful as analgesics and sedatives. Some are also useful as major (antipsychotics) and/or minor (anxiolytics) tranquilizers, muscle relaxants, or hypotensives. The compounds of this invention are made by (1) reaction of .DELTA..sup.4a,9b -tetrahydro precursors with borane/THF and (2) acidifying the reaction product by which it is reduced and hydrolyzed to form the corresponding trans-hexahydro compound.
某些转-2,3,4,4a,5,9b-六氢-1H-吡啶[4,3-b]吲哚化合物可用作镇痛剂和镇静剂。其中一些也可用作主要(抗精神病药)和/或次要(抗焦虑药)镇定剂、肌肉松弛剂或降压剂。本发明的化合物是通过以下方法制备的:(1)将.DELTA.4a,9b-四氢前体物与硼烷/四氢呋喃反应,(2)酸化反应产物,从而还原和水解形成相应的转-六氢化合物。
