A General Route to the Synthesis of 1,5-Methano- and 1,5-Ethano- 2,3,4,5-tetrahydro-1H-3-benzazepines
摘要:
A general approach to preparing 1,5-methano-(1) and 1,5-ethano-2,3,4,5-tetrahydro-1H-3-benzazepine (2) is discussed. This strategy involves converting an indanone or tetralone (4) to a cyanohydrin (3) which is subjected to hydrogenolysis followed by lactamization and reduction to provide bicyclic aryl piperidine (1) and bicyclic aryl homopiperidine (2).
Compounds of the formula
and their pharmaceutically acceptable salts, wherein R1, R2, and R3 are as defined herein; intermediates for the synthesis of such compounds, pharmaceutical compositions containing such compounds; and methods of using such compounds in the treatment of neurological and psychological disorders.
