Heterocyclic Compounds from Lactones, Lactams and Thiollactones, XIV1). - On the Reaction of α-Acetyl-γ-butyrolactone with Heterocyclic Aminesα-Acetyl-γ-butyrolactone (1) reacts with 2-aminopyridines (2a-c), 2-amino-Δ1-pyrroline (9), -isoindole (12), -Δ2-imidazoline (15), and -Δ2-1,4,5,6-tetrahydropyrimidine (16) to form condensed heterocyclic systems, such as pyrido- (3a-c), pyrrolo- (10, 11), imidazo- (17), and pyrimido[1,2-α]pyrimidines (18). The structures of these products are in agreement with the spectroscopic data (UV, IR, NMR).
