(4R)-Ethyl 4-(4-chlorophenyl)-2-hydroxy-5-oxo-2,3,4,5-tetrahydropyrano[3,2-c]chromene-2-carboxylate

(4R)-Ethyl 4-(4-chlorophenyl)-2-hydroxy-5-oxo-2,3,4,5-tetrahydropyrano[3,2-c]chromene-2-carboxylate

The title compound, C21H17ClO6, is optically pure and adopts an R configuration. It was obtained by an organocatalytic asymmetric Michael addition of 4-hydroxycoumarin with (E)-ethyl 4-(4-chlorophenyl)-2-oxobut-3-enoate. The structure consists of a tetrahydropyran unit fused to the coumarin ring rin...
