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.
11H-Pyrrolo[2,1-b][3]benzazepin-11-one及其衍生物通常通过N-苯乙烯基吡咯-2-羧酸衍生物的Friedel-Crafts环合成制备。它们是合成骨骼肌松弛剂和镇静剂的有用中间体,如11-(3-二甲基氨基丙基亚甲基)-2-氰基-11H-吡咯[2,1-b][3]苯并噻唑啉。
