Abstract
Abstract 2-Acetyl-1,3-indandione Derivatives, Amines, Diazonium Salts 2-Acetyl-1,3-indandione (1) undergoes the Mannich reaction with piperidine or diethyl-amine hydrochloride to give compounds 2 and 3, respectively. On treatment 1 with ethylenediamine hydrochloride and formaldehyde, 2,2′-[ethylene bis[imino(1-oxotri-methylene)]]di-1,3-indandione (4) was obtained. With primary aromatic amines it yielded 2-[N-(substituted phenyl)acetimidoyl]-1,3-indandione (5a-i). The condensation of 1 with o-aminophenol yielded a mixture of 5c and the oxazepinone (6), while condensation with 2,3-diaminopyridine gave the diazepinone (7). Mannich reaction of 5a and g with piperidine hydrochloride and formaldehyde gave 8a, b. The coupling of 1 with diazonium salts was investigated.
