4-Hydroxy-3-[(4-hydroxy-6-methyl-2-oxo-3,6-dihydro-2H-pyran-3-yl)(3-thienyl)methyl]-6-methyl-3,6-dihydro-2H-pyran-2-one
The asymmetric unit of the title compound, C(17)H(14)O(6)S, contains four crystallographically independent mol-ecules in which the pyran-one units are essentially planar, with maximum deviations of 0.016 (2), 0.019 (2), 0.025 (2), 0.014 (2), 0.020 (2), 0.010 (2), 0.003 (2) and 0.012 (2) Å. One of the thio-phene rings is disordered over two positions, with an occupancy ratio of 0.739 (4):0.261 (...

In the title compound, C(13)H(12)O(3), the pyran ring adopts a half-chair conformation with a C atom deviating from the least-squares plane of the remaining ring atoms by 0.606 (2) Å. This plane and that of the benzene ring make a dihedral angle of 44.18 (6)°. In the crystal, mol-ecules are linked through O-H⋯O hydrogen bonds into infinite chains along the b axis, and these chains are cross-lin...

In the title compound, C(13)H(12)O(2), the dihedral angle between the pyran-one and phenyl rings is 57.55 (9)°. In the crystal, the mol-ecules are linked by π-π stacking inter-actions between the parallel pyran-one rings of neighboring mol-ecules with distances of 3.5778 (11) Å and 3.3871 (11) Å between the planes. C-H⋯O interactions also occur.
