Abstract
The reaction of 9,10-dimethylacridinium methosulfate with aromatic o-hydroxy aldehydes in alcohol in the presence of piperidine gives 10-methyl-4′-(10-methyl-9-acridanylidenemethyl)-spiro[acridan-9,2′-chromans]. The structure of the compounds obtained was established by means of the PMR, UV, and IR spectra.
