rac-6-Ethoxy-3,3a,4,9b-tetrahydro-1,3-diphenyl-1H-chromeno[4,3-c]isoxazole-3a-carbonitrile
The title compound, C(25)H(22)N(2)O(3), with three stereogenic centres, crystallizes in a centrosymmetric space group as a racemate. The pyran ring adopts a sofa conformation and the five-membered isoxazole ring exhibits an envelope conformation. The dihedral angle between the benzene ring and the mean plane through the near coplanar atoms of the pyran ring is 10.54 (9)°. In the crystal, no sig...
متن کامل3-Acetyl-1,5-diphenyl-1H-pyrazole-4-carbonitrile
The title compound, C(18)H(13)N(3)O, has a butterfly-like structure, in which the pyrazole ring forms dihedral angles of 59.31 (8) and 57.24 (8)° with the two phenyl rings. The dihedral angle between the two phenyl rings is 64.03 (8)°. The pyrazole ring and the C-C=O plane of the acetyl group are twisted slightly, making a dihedral angle of 7.95 (18)°. In the crystal, mol-ecules are linked thro...
متن کاملCrystal structure of rac-2,3-diphenyl-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-one 1-oxide
In the title compound, C16H15NO2S [alternative name: rac-2,3-diphenyl-1,3-thia-zinan-4-one 1-oxide], the thia-zine ring exhibits an envelope conformation, with the S atom forming the flap. The sulfoxide O atom is in a pseudo-axial position on the thia-zine ring and is trans to the phenyl group on C-2. The phenyl rings form a dihedral angle of 89.47 (19)°. In this racemate crystal, homochiral mo...
