4-Oxo-2-phenylchroman-6-yl propionate

In the structure of the title compound, C(18)H(16)O(4), both the S and R enanti­omers appear to occupy in a random way four symmetry-equivalent sites of the unit cell in an approximately 4:1/1:4 ratio. The chiral C atom of the pyrone ring together with the phenyl ring bonded to this atom are disorde...

description In the structure of the title compound, C(18)H(16)O(4), both the S and R enanti­omers appear to occupy in a random way four symmetry-equivalent sites of the unit cell in an approximately 4:1/1:4 ratio. The chiral C atom of the pyrone ring together with the phenyl ring bonded to this atom are disordered over two positions, the occupancy factor of the major component being 0.809 (5). Adjacent molecules are linked by weak C—H⋯O hydrogen bonds.
