Ethyl 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.

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 ...

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 2-[({[4-amino-5-cyano-6-(methylsulfanyl)pyridin-2-yl]carbamoyl}methyl)sulfanyl]acetate monohydrate
The title compound, C13H16N4O3S2·H2O, crystallizes in a 'folded' conformation with the ester group lying over the carbamoyl moiety, with one solvent water mol-ecule. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯O hydrogen bond, and an N-H⋯O hydrogen-bonding inter-action involving the lattice water mol-ecule. The packing involves N-H⋯N, N-H⋯O, O-H⋯N and O-H⋯O hydrogen bond...
