Condensation of 4-azafluorene with γ-butylene glycol and glycerin

1,4-Di (4-azafluoren-9-yl) butane and 9-(δ-hydroxybutyl)-4-azafluorene were obtained by condensing 4-azafluorene with γ-butylene glycol. From the first of these products, 1,4-di(7-aza-3-oxo-1,2,3,10b-tetrahydrofluoranthen-10b-yl)butane was synthesized by a series of successive transformations (cyanoethylation, hydrolysis, dehydrocyclization). In the condensation of 4-azafluorene with glycerin, 1,2,3-tri(4-azafluoren-9-yl) propane was obtained. © 1986 Plenum Publishing Corporation
