2-(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...

In the mol-ecule of the title compound, C(16)H(13)N(3)O(4), the atoms of the spiro pyran ring are nearly planar with a maximum deviation of 0.095 (2) Å. The indole and pyran rings are oriented at a dihedral angle of 87.3 (9)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯N and N-H⋯O hydrogen bonds.
متن کاملMethyl (2E)-2-cyano-3-(dimethylamino)prop-2-enoate
In the title compound, C(7)H(10)N(2)O(2), the dimethyl-amino group is twisted slightly relative to the acrylate fragment, forming a dihedral angle of 11.6 (1)°. In the crystal, molecules are linked via pairs of bifurcated C-H/H⋯O hydrogen bonds, forming inversion dimers, which are further connected by C-H⋯N hydrogen bonds into chains along the a-axis direction.
متن کاملTriphenylphosphine 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 ...
