Abstract
The efficient one-pot synthetic approaches for benzopyranobenzopyrans and naphthopyranobenzopyrans are described. The key strategies involve ethylenediamine diacetate-catalyzed cyclization by domino aldol-type reaction/hetero Diels-Alder reaction of resorcinols and naphthols to benzaldehydes with O-allyl ether groups. These reactions provide a rapid route for the synthesis of novel types of polyheterocycles with stereochemically defined quaternary carbon centers.
