rac-(1S,2R)-Diethyl 6-hydr­oxy-1-(4-methoxy­phen­yl)-3-oxo-2,3-di­hydro-1H-benzo[f]chromen-2-yl]­phospho­nate

In the title compound, C(24)H(25)O(7)P, the δ-valerolactonyl ring exists in a distorted screw-boat conformation with the diethoxy­phosphoryl substituent occupying an axial position. The latter adopts an almost syn-periplanar conformation around the P—C bond. The mol­ecules form centrosymmetric dimer...

Sumario:In the title compound, C(24)H(25)O(7)P, the δ-valerolactonyl ring exists in a distorted screw-boat conformation with the diethoxy­phosphoryl substituent occupying an axial position. The latter adopts an almost syn-periplanar conformation around the P—C bond. The mol­ecules form centrosymmetric dimers connected by O—H⋯O hydrogen bonds.
