Abstract
A simple and efficient method for the synthesis of a new type of unsymmetrical cross-conjugated system based on 2-arylidene-5-((dimethylamino)methylene)cyclopentanone by reaction of 2-arylidenecyclopentanones with dimethylformamide dimethyl acetal catalyzed by DBU was discovered. The preparation of target compounds on a gram-scale is considered. The fluorescent properties of the synthesized systems are considered depending on the structure ofchloroform.
