The title compound, C(28)H(28)N(2)O(4), was synthesized by the reaction of 2-acetyl-1-naphthol with 1,4-bis-(amino-oxy)butane in ethanol. The molecule, which lies about an inversion centre, adopts a linear structure, in which the oxime groups and naphthalene ring systems assume an anti conformation. The intra-molecular inter-planar distance between parallel naphthalene rings is 1.054 (3) Å. Int...

melamine trisulfonic acid (mtsa) is utilized as a highly efficient catalyst for the solvent-free condensation reaction of 2-naphthol (2 eq.) with arylaldehydes (1 eq.) under conventional thermal as well as microwave conditions to give the d

In short-term organ cultures of normal human peripheral lung, phenolic substrates are metabolized predominantly to sulphate ester conjugates with little or no glucuronic acid conjugates being formed (Mehta & Cohen, 1979). However, with shortterm organ culture of tumour tissue from the lung of the same patients, the converse appears true (R. Mehta & G. M. Cohen, unpublished work). The rationale ...

The title compound, C(22)H(18)N(2)O, was synthesized from naphthalen-2-ol, benzaldehyde and pyridin-2-amine. In the crystal, mol-ecules are linked into centrosymmetric R(2) (2)(16) dimers by pairs of O-H⋯N hydrogen bonds. The mol-ecular conformation is stabilized by an N-H⋯O hydrogen bond. The dihedral angle between the naphthylene ring system and the phenyl ring is 72.86 (12)°.
