An efficient synthesis of 6H,7H-chromeno[4,3-b]chromenes and 6,7-dihydrothio chromeno[3,2-c]chromenes as 9-substituted xanthene like analogs

An efficient synthetic route with good overall yields to access 7-aryl/heteroaryl/alkyl substituted 6H,7H-chromeno[4,3-b]chromene, and 6,7-dihydrothiochromeno[3,2-c]chromene scaffolds has been developed. The route to these xanthene-like analogs involves a
