SYNTHESIS METHOD OF PYRANOSTILBENES USING DOMINO ALDOL-TYPE REACTION/6π-ELECTROCYCLIZATION REACTION

摘要

PURPOSE: A method for synthesizing pyranostilbene compound is provided to quickly and simply synthesize pyranostilben compound in a high efficiency. CONSTITUTION: A compound of chemical formula 2 or 3 is synthesized by domino aldole reaction and six pi-electrocyclic reaction of a compound of chemical formula 1 and alpha,beta-unsaturated aldehyde under the presence of benzene or xylene reflux using diethylene diamine diacetate(EDDA).
