Novel synthetic routes to nitrogen-bridged tricyclic derivatives of pyrrolo[2,1,5-cd]indolizine and pyrrolo[2,1,5-de]quinolizine derived from 2-acyl-N-(acylmethyl)pyridinium halides

Novel synthetic routes to nitrogen-bridged derivatives of pyrrolo[2,1,5-cd]indolizine and pyrrolo[2,1,5-de]-quinolizine were developed starting from 2-acyl-N-(acylmethyl)pyridinium halides. Thus, 2-benzoyl-N-phen-acylpyridinium bromide (1) afforded 3,4-di

A NOVEL SYNTHESIS OF PYRROLOQUINOLIZINONES(CYCLAZINONES)

3H-Pyrroloquinolizin-3-ones and a 5H-pyrroloquinolizin-5-one were synthesized by the intramolecular aldol condensation of the appropriate 3,5-diacylindolizines.
