Quinazolyl-2-propionic acid hydrochloride (5) was synthesized by reduction of N-(o-nitrobenzyl)succinimide with tin chloride. A pyrroloquinazolin-1-one 4, 3,9-dihydropyrrolo[2,1-b]quinazolin-1(2H)-one} was prepared in 68% yield by heating 5 in Ac2O and subsequent treatment with Et3N. Compound 4 was obtained in 71% yield in one step by reduction of N-(o-nitrobenzyl)succinimide with Fe in the presence of HCl. Compound 4 was protonated, alkylated, and acylated on the N(4) atom. Derivatives of quinazolyl-2-propionic acid and 1-(2-aminobenzyl)succinimide were prepared by reaction of derivatives of 4 with nucleophilic reagents.

diverse range of kinetically controlled angular and thermodynamically controlled linear tricyclic and tetracyclic 1,3-diaza-heterocycles have been described via the intramolecular cyclizations of the corresponding imides/anilic acid esters. The effect of imide stability on the angular/linear product selectivity has also been described. The kinetically controlled angular products were successfully transformed
