Ethyl 6-amino-5-cyano-4-phenyl-2,4-dihydropyrano[2,3-c]pyrazole-3-carboxylate dimethyl sulfoxide monosolvate
In the asymmetric unit of the title compound, C16H14N4O3·C2H6OS, there are two independent main mol-ecules (A and B) and two dimethyl sulfoxide solvent mol-ecules. In mol-ecule A, the pyran ring is in a flattened sofa conformation, with the sp (3)-hydridized C atom forming the flap. In mol-ecule B, the pyran ring is in a flattened boat conformation, with the sp (3)-hydridized C atom and the O a...
متن کامل2-Amino-6-{[(6-chloropyridin-3-yl)methyl](ethyl)amino}-1-methyl-5-nitro-4-phenyl-1,4-dihydropyridine-3-carbonitrile ethanol monosolvate
In the title compound, C(21)H(21)ClN(6)O(2)·C(2)H(6)O, a member of the insecticidal active neonicotinoid group of compounds, the 1,4-dihydro-pyridine ring adopts a boat conformation. An intra-molecular C-H⋯O hydrogen bond occurs while the components are linked by an N-H⋯O interaction. The crystal packing is stablized by O-H⋯N hydrogen bonds and C-H⋯O interactions.

In the title compound, C(23)H(22)N(2)O(3), the pyran ring adopts a twisted boat conformation. The tolyl rings and carboxyl-ate group are attached to the pyran ring with torsion angles of -77.1 (2), 59.5 (3) and 17.8 (3)°, respectively. The ethyl group is disordered over two orientations with a site-occupancy ratio of 0.508 (5):0.492 (5). In the crystal, mol-ecules are linked by N-H⋯N and N-H⋯O ...
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.
متن کاملEthyl 6-amino-5-cyano-4-isopropyl-2-methyl-4H-pyran-3-carboxylate
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.
