Crystal structure of 2-amino-3-cyano-4-(4-methoxyphenyl)-4H-1-benzothieno[3,2-b]pyran
The three fused five- and six-membered rings in the title compound, C19H14N2O2S, are virtually coplanar, with the maximum deviation from the mean plane being 0.060 (1) Å. This benzothieno[3,2-b]pyran ring system is nearly perpendic-ular to the plane of the 4-meth-oxy-phenyl ring, forming a dihedral angle of 83.65 (5)°. In the crystal, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds into ...

In the title compound, C21H24ClN3O3, the dihedral angle between the pyran ring (r.m.s. deviation = 0.037 Å) and the chloro-benzene ring is 88.56 (14)°. In the crystal, the mol-ecules are linked by C-H⋯O inter-actions, generating C(7) (001) chains.

In the title compound, C(13)H(18)N(2)O(3), the two H atoms of the NH(2) group are engaged in hydrogen bonding with the N atom of the cyano group and with one O atom of the ethoxy-carbonyl group, building a chain parallel to the [100] direction. The N-H⋯N hydrogen bonds assemble the mol-ecules around inversion centres, forming dimers with an R(2) (2)(12) graph-set motif.
متن کاملEthyl 6-amino-5-cyano-2-methyl-4-propyl-4H-pyran-3-carboxylate
The pyran ring of the title compound, C(13)H(18)N(2)O(3), is almost planar (r.m.s. deviation = 0.059 Å). The crystal packing is stabilized by N-H⋯O and N-H⋯N hydrogen bonds.
