A series of 2-amino-4-(nitroalkyl)-4H-chromene-3-carbonitriles were synthesized by an efficient multicomponent reaction in aqueous media using DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) as a catalyst at room temperature. Mild condition, environment friendly procedure and excellent yields are the main advantages of this procedure. The cytotoxic activity of target compounds were evaluated against t...
In the title compound, C(14)H(14)N(2)O(2), the dihedral angle between the two benzene rings is 9.67 (10)°. Two intra-molecular O-H⋯N and N-H⋯N hydrogen bonds involving the hydr-oxy and amino groups generate S(6) and S(5) ring motifs, respectively. In the crystal structure, N-H⋯O hydrogen bonds link neighboring mol-ecules. Mol-ecules are also stacked in a head-to-tail fashion along the c axis th...
In the title hydrated salt, C(6)H(9)N(2)O(+)·C(14)H(9)O(3) (-)·H(2)O, the dihedral angle between the benzene rings of the 2-benzoyl-benzoate anion is 82.04 (14)°, while the angles between the aromatic ring of the pyridinium cation and each of the benzene rings of the anion are 4.42 (14) and 82.04 (14)°. In the crystal, mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds, generating a three-...
