In the title compound, C(16)H(15)NO(4), a potential bidentate N,O-donor Schiff base ligand, the benzene rings are inclined to one another by 4.24 (12)°. The mol-ecule has an E conformation about the C=N bond. An intra-molecular O-H⋯N hydrogen bond makes an S(6) ring motif. In the crystal, pairs of O-H⋯O hydrogen bonds link the mol-ecules, forming inversion dimers with R(2) (2)(8) ring motifs. T...

The title compound, C(13)H(17)NO(2), has an intra-molecular N-H⋯O hydrogen bond, forming a planar six-membered ring with a mean deviation of 0.015 (5) Å from the plane. This plane makes a dihedral angle of 7.19 (8)° with the adjacent phenyl ring. Through an inter-molecular O-H⋯O hydrogen bond, the mol-ecules with their 2(1) screw and b-translation equivalents form a helical chain running parall...

synthesis of 2-[2-(2,6-dichlorophenyl)amino]phenylmethyl-3-[4-(2-substitutedphenyl-4-oxo-thiazolidinyl)aryl]-6-bromo quinazolin-4(3h)ones via-j have been achieved from the starting material 2-[(2,6-dichlorophenyl)amino] phenylacetic acid i to benzoxazine iii, further reaction with p-phenylindiamine and substituted aromatic aldehyde gave 2-[2-(2,6-dichlorophenyl)amino]phenyl methyl-3-(4-aminoary...
