An efficient approach for the synthesis of novel methyl sulfones in acetic acid medium and evaluation of antimicrobial activity

A series of nine methyl sulphones (3a-3i) starting from the aldehydes (1a-1i) were synthesized in two consecutive steps. In the first step, preparation of allyl alcohols (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 (85%-95%), and the products were obtained with good purity. All the synthesized compounds were characterized by their 1H, 13C 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 Gram 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.

Iron (III) chloride-catalyzed direct sulfonylation of alcohols with sodium arenesulfinates

A new protocol for the direct sulfonylation of benzylic, allylic and homoallylic alcohols with sodium arenesulfinates is described by using iron (III) chloride as a catalyst and chlorotrimethylsilane as an additive. This method requires no preactivation o

Studies of Sulfinyl Radicals. 1. Thermal Decompositions of Benzhydryl p-Tolyl Sulfoxide and Benzhydryl Methyl Sulfoxide

The kinetics and mechanism of the thermal decompositions of benzhydryl p-tolyl sulfoxide (BTSO) and benzhydryl methyl sulfoxide (BMSO) were studied.Product analysis, ESR, and CIDNP results showed that both sulfoxides gave p-toluenesulfinyl and methanesulfinyl radicals, respectively, by the scission of carbon-sulfur bonds at 100-130 deg C.The presence of a small amount of a base such as pyridine has been found to suppress the formation of other products than the coupling products (the corresponding thiosulfonates and tetraphenylethane), which may be formed by ionic reactions of BTSO and BMSO.The mechanism of BTSO decomposition is complex, since it is in equilibrium with benzhydryl p-toluenesulfenate (BTSN) at 100-130 deg C.On the other hand, BMSO, showing simple decomposition behavior, indicated that the decomposition rates decreased on the addition of hydroxylic solvents.
