Abstract :A series of nine methyl sulphones insert ignore into journalissuearticles values(3a-3i); starting from the aldehydes insert ignore into journalissuearticles values(1a-1i); were synthesized in two consecutive steps. In the first step, preparation of allyl alcohols insert ignore into journalissuearticles values(2a-2i); from their corresponding aldehydes by the reaction of sodium borohydride in methanol at room temperature is reported. Finally, methyl sulphones are synthesized by condensing sodium methyl sulfinates with allyl alcohols in the presence of BF3.Et2O in acetic acid medium at room temperature for about 2-3 h. The reaction conditions are simple, yields are high insert ignore into journalissuearticles values(85%-95%);, and the products were obtained with good purity. All the synthesized compounds were characterized by their H-1,C-13 NMR, and mass spectral analysis. All the title compounds were screened for antimicrobial activity. Among the compounds tested, the compound 3f has inhibited both Gram positive and Grain negative bacteria effectively and compound 3i has shown potent antifungal activity. These promising components may help to develop more potent drugs in the near future for the treatment of bacterial and fungal infections.
