Crystal structure of ethyl (4R)-2-amino-7-hydroxy-4-phenyl-4H-chromene-3-carboxylate
In the title compound, C(18)H(17)NO(4), the dihedral angle between the phenyl ring and the fused six-membered ring is 77.65 (4)°. The conformation of the molecule is determined in part by an intramolecular N—H⋯O hydrogen bond between the amino H atom and the carbonyl O atom, forming an S(6) motif....
