A novel aza-Prins type cyclization reaction involvingN-acyliminium ions and amides is reported for the synthesis of tetrahydropyrimido[2,1-a]isoindole-2,6-dione and 6,6a-dihydroisoindolo[2,1-a]quinazoline-5,11-dione derivatives in excellent yields. The strategy features inexpensive reagents, mild reaction conditions, and metal-free synthesis of N-heterocyclic frameworks. Further, post-synthetic modification results in the unprecedented formation of its triazole, tetracyclic diazacyclopenta[def]phenanthrene-1,4(9a1H)-dione and carbonyl derivatives.

The o-, m-, and p-phthalimidobenzoic acid azides (IIa-c) have been synthesized via the reaction of the corresponding acid chlorides (Ia-c) with aq.NaN3 in acetone.The base-catalyzed decomposition of IIa-c with aromatic amines and/or hydrazines shows that
