摘要:
11H-Pyrrolo[2,1-b][3]benzazepin-11-one and derivatives thereof are generally prepared by Friedel-Crafts ring closure of a N-styrylpyrrole-2-carboxylic acid derivative. They are useful intermediates in the synthesis of skeletal muscle relaxants and tranquilizers such as 11-(3-dimethylaminopropylidene)-2-cyano-11H-pyrrolo[2,1-b][3]benzazepine.
摘要:
(9-Carboxy-11H-pyrrolo[2,1-b][3]benzazepine-11-ylidene)piperidines useful as appetite stimulants, are prepared by hydrolysis of the corresponding ester or cyano derivatives.
摘要:
Pyrrolo[2,1-b][3]benzazepines with a piperidinylidene group in the 11-position have utility as antipsychotic agents. They also demonstrate antiserotonin and antihistaminic activity. They are prepared by reaction of a pyrrolo[2,1-b][3]benzazepin-11-one with a piperidinyl magnesium halide followed by dehydration.
