  • The naphthol derivatives (IV) and (IV') according to the present invention are the novel compounds and are compounds wherein an optionally substituted a pyridyl, thiazolyl, benzothiazolyl or imidazolyl group is added at the 3-position and/or6-position of 2-hydroxynaphthalene through an aminocarbonyl group or --CONHCONH-- group.

  • In continuation of our efforts to explore newer reactions for the synthesis of heterocyclic compounds, we wish to report here a facile and improved protocol for preparation of 2′-aminobenzothiazolo-arylmethyl-2-naphthols from β -naphthol, aromatic aldehydes, and 2-aminobenzothiazole in the presence of NBS as a catalyst under solvent-free conditions (Scheme 1 ).
