Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The condensation of 1-(1,3-indanedion-2-ylidene)-2-acenaphthenone with imines of β-dicarbonyl compounds gave 2,5′-dioxospiro 1,4′,acenaphthene-1′,4′-dihydroindeno-[3,2-b]pyridines. Oxidation of the pyridines with air oxygen at room temperature without catalysts brings about cleavage of the C-C bond to give 8-(5-oxoindeno[3,2-b]-4-pyridyl)-1-naphthoic acids.
