Abstract
Addition Reactions of 2-Amino-1-azetines with Cyclopropenones; Formation of Azepine Derivatives by Ring Expansion Reactions. The reaction of 2-amino-1-azetines of type 6 with 2,3-diphenylcyclopropenone (1a) in acetonitrile leads to azeto[1,2-a]pyrroles (cf: 7 and 9, Schemes 3 and 4) in good yield. It is remarkable that in the reaction of 6a with 1a only endo-7 is formed. With silicagel in ether endo-7 isomerizes to the thermodynamically more stable exo-7 (Schemes 3 and 6). The crystal structure of the latter compound has been establis
