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(6)H(6)O(4), inter- and intra-molecular hydrogen bonds are observed which help to establish the crystal structure. There are weak π-π interactions between pyran rings separated by 3.5692 (9) Å.
متن کامل5-Hydroxy-2-methyl-4H-pyran-4-one
The title compound, C(6)H(6)O(3), is a member of the pyrone family. The mol-ecules are planar (r.m.s. deviation of the asymmetric unit is 0.0248 Å, whereas that of the dimer is 0.0360 Å) and they are dimerized due to inter-molecular O-H⋯O hydrogen bonds. The dimers are connected to each other through hydrogen bonds involving the CH(3) group and the hydr-oxy O atom. There are π-π inter-actions b...
متن کاملSoyasaponins and Related Glycosides of Desmodium canadense and Desmodium illinoense
Seed extracts of Desmodium canadense (L.) DC., a native Canadian legume, were examined by HPLC and electrospray ionization mass spectrometry (LC/MS) for the presence of triterpenoid saponins of the oleanene type. An aqueous methanol extract, fractionated by use of a DiaionTM HP-20 macroporous resin, was found to possess soyasaponin III (soyasaponin Bb ́) and the 2,3-dihydro-2,5-dihydroxy-6-methy...
متن کامل2-(4-Methoxyphenoxy)-6-methyl-3-oxo-3,6-dihydro-2H-pyran-4-yl benzoate
The title compound, C(20)H(18)O(6), has been synthesized from 4-methoxy-phenyl 3-O-benzo-yloxy-α-l-rhamnopyran-oside by oxidation on treatment with pyridinium dichromate in the presence of acetic anhydride. In the mol-ecule, the pyran ring adopts an envelope conformation with the O atom at the flap position. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
