Triphenylphosphine Catalysed Facile Multicomponent Synthesis of 2-Amino-3-Cyano-6-Methyl-4-Aryl-4H-Pyrans
Triphenyl phosphine(PPh3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4H-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in EtOH-H2O (1:1) at reflux conditions. The results show that ...
متن کاملDesign and Synthesis of 2-Methyl and 2-Methyl-4-Nitro Imidazole Derivatives as Antifungal Agents
Two series (a and b) of N- substituted heteroaromatic compounds related to clotrimazole were synthesized. Imidazole ring of the clotrimazole was replaced by 2-methylimidazole in series a, and by 2-methyl-4-nitroimidazole in series b. O-cholortrityl moiety of clotrimazole was also replaced by trityl, mono or dimethoxy trityl. Chemical structures...
متن کامل(4RS)-Methyl 4-cyano-4-cyclohexyl-4-phenylbutanoate
In the crystal structure of the title compound, C(18)H(23)NO(2), there are only van der Waals inter-actions present. The cyclo-hexyl ring has a chair conformation. The longer axes of the displacement parameters of the non-H atoms forming the ethyl-methyl-carboxyl-ate skeleton are perpendicular to the plane through the non-H atoms of this skeleton.

متن کامل2-(3-Cyano-4-methyl-5,5-diphenyl-5H-furan-2-ylidene)malononitrile
The title compound, C21H13N3O, crystallizes with two independent molecules with similar conformations per asymmetric unit. The dihydrofuran rings are essentially planar with maximum deviations of 0.017 (1) and 0.006 (1) Å for the O atoms. The dihedral angles between the di-hydro-furan ring and the attached phenyl rings are 79.90 (6) and 82.07 (6)° in one mol-ecule and 79.36 (6) and 72.26 (6)° i...
