Tert-Butyl 6-benzoyl-5-hydr-oxy-2-oxo-2H-chromene-4-carboxyl-ate.

ABSTRACT: In the title compound, C(21)H(18)O(6), a previously unknown coumarin derivative, the benzoyl substitutent makes a dihedral angle of 53.80?(16)° with the plane of the coumarin rings. An intramolecular O-H?O hydrogen bond is observed.
