tert-Butyl 6-amino-5-cyano-2-(2-methoxyethyl)nicotinate
The title compound, C(14)H(19)N(3)O(3), was synthesized by the reaction of 3-meth-oxy-propionitrile, tert-butyl bromo-acetate and eth-oxy-methyl-enemalononitrile. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into chains propagating along the b axis.
متن کاملCrystal structure of N-[4-amino-5-cyano-6-(methylsulfanyl)pyridin-2-yl]-2-(cyclohexylsulfanyl)acetamide
In the title mol-ecule, C15H20N4OS2, the acetamido fragment is nearly coplanar with the pyridyl ring [C-N-C-C torsion angle = -4.1 (2)°], while the cyclo-hexyl-sulfanyl portion protrudes from this plane [N-C-C-S torsion angle = -40.8 (6)°]. In the crystal, alternating pairwise N-H⋯O and N-H⋯N hydrogen bonds across inversion centres form chains along [101], which are associated into stepped laye...
متن کاملCrystal structure of N-[4-amino-5-cyano-6-(methylsulfanyl)pyridin-2-yl]-2-chloroacetamide
In the title compound, C9H9ClN4OS, the dihedral angle between the acetamide moiety and the pyridine ring is 4.83 (12)°. The O=C-C-Cl torsion angle is 46.4 (3)° and an intra-molecular C-H⋯O inter-action generates an S(6) ring. In the crystal, mol-ecules are linked by N-H⋯O, N-H⋯N and C-H⋯N hydrogen bonds, generating sheets lying parallel to (120).
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 ...
متن کاملMethyl 6′-amino-5′-cyano-2′-methyl-2-oxospiro[indoline-3,4′-pyran]-3′-carboxylate
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.
