Direct cyclization of ortho-(1H-pyrrol-1-yl)aryl and heteroaryl carboxylic acids into fused pyrrolizinones
摘要:
A series of fused heterocyclic compounds based on a pyrrolizinone structure have been prepared from ortho-(1H-pyrrol-1-yl)aryl and heteroaryl carboxylic acids by intramolecular Friedel-Crafts acylation promoted by bis(trichloromethyl) carbonate, in generally good yield without using Lewis acid catalysts.

Compounds represented by the general formula (1):
[wherein R1 is typically an aminoalkyl group; R2 is typically a hydrogen atom, a lower alkyl group, R3 or SR4 (where R4 is typically a lower alkyl group); Ar is typically a 5-membered aromatic heterocyclic group] have an NOS inhibiting activity and are useful as therapeutics of cerebrovascular diseases and other pharmaceuticals.
