Abstract

ABSTRACT: A novel series of bis (phenylimino dihydro thiazolyl-2 H -chromene) derivatives have been synthesized through an efficient one-pot multicomponent approach involving different substituted of 3-(2-bromoacetyl)-2 H -chromen-2-ones, phenyl isothiocyanates and para -phenylenediamine in presence of dimethylformamide solvent. The target compounds were obtained in a shorter reaction time through simple reaction work up with good yields. All the synthesized products were characterized by their spectral and analytical data like IR, 1 H NMR, 13 C NMR, Roesy, and mass spectral data. GRAPHICAL ABSTRACT:
