3,5-Dihydroxy-2-methyl-4H-pyran-4-one
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 کامل4-Amino-3,5-dimethyl-4H-1,2,4-triazole
In the title compound, C(4)H(8)N(4), inter-molecular N-H⋯N hydrogen bonds involving the amino groups and triazole N atoms form a two-dimensional sheet.
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...

The title compound, C(30)H(25)Cl(2)NO(3), was prepared by the reaction of 3-oxo-N,3-diphenyl-propane-thio-amide, 2,5-dichloro-benzaldehyde and 5,5-dimethyl-1,3-cyclo-hexa-nedione (1:1:1) in ethanol. The cyclohexene ring adopts a half-chair conformation. The crystal structure exhibits intra-molecular N-H⋯O and C-H⋯O, and inter-molecular C-H⋯O inter-actions.
متن کاملSynthesis and Antimicrobial Evaluation of 4H-Pyrans and Schiff Bases Fused 4H-Pyran Derivatives as Inhibitors of Mycobacterium Bovis (BCG)
The focus of our study is the synthesis and biological activity evaluation of a series of 4H-Pyran compounds and schiff bases fused 4H-Pyran derivatives which are known to possess a wide variety of biological activities. In this paper at first a simple and efficient one-pot synthesis of 4H-Pyran s from the three-component reaction between malononitrile, aldehydes, and active methylene compounds...
