Ethyl 2-amino-4-(4-methyl-1,3-thiazol-5-yl)-5-oxo-4H,5H-pyrano[3,2-c]chromene-3-carboxylate
There are two independent molecules in the asymmetric unit of the title compound, C(19)H(16)N(2)O(5)S, in which the thiazole rings make dihedral angles of 80.89 (11) and 84.81 (11)° with the pyrano[3,2-c]chromene ring systems. An intramolecular N—H⋯O hydrogen bond involving the amino group occurs...
