. Reacting 1a,b,d with 4-azidomethylcarbonylantipyrine 8 gave 2-aminopyrrole (14). Pyrano[3,2-c] quinolines (20a,b and 23) were obtained by reacting 4-hydroxyquinoline (15) with 1g, h;2b, respectively.Reaction of 1 with naphthalenediols 24,27 and 29 yield naphthodipyrans 26a,b,28a,b and 30a,b, respectively. Spironaphthodipyrans (32,33) and spironaphthopyrans (36,37) were prepared through reaction ...
