Abstract
In present work, novel derivatives of substituted N-(4-(8-methoxy-2-oxo-2H-chromen-3-yl) thiazol-2-yl) amide have been synthesized. The solvent free reaction of 2-Hydroxy-3-methoxybenzaldehyde with Ethyl acetoacetate in presence of Piperidine catalyst produces 3-acetyl-8-methoxy-2H-chromen-2-one (C). Compound C was α- brominated using CuBr2and subsequently cyclized using Thiourea to produce 3-(2-aminothiazol-4-yl)-8-methoxy-2H-chromen-2-one as main scaffold (E). This scaffold E was finally reacted with different Acid chloride to isolate title compound derivatives. The chemical structures of synthesized compounds were confirmed by1H-NMR, FT-IR and Mass spectral/LCMS analysis. The synthesized compounds were screened for potential Antimicrobial, Antifungal and Antimalarial activity.
