Abstract
Synthesis of novel 2-(4-methoxy benzene sulfonyl)-1,3-dimethyl/1-methyl-3-phenyl/1,3-diphenylpropane-1, 3-dione and 2- (4-methylthio benzene sulfonyl)-1-methyl-3-phenyl/1,3-diphenyl/1-methyl-3-ethoxy propane-1,3-dione
Author(s): Suresh Singh Chauhan, Y.C.JoshiAn efficient synthesis of novel 2-(4-methoxy benzene sulfonyl)-1,3-dimethyl/ 1-methyl-3-phenyl/1, 3-diphenyl propane-1, 3-dione(IIa-c) and 2-(4- methylthio benzene sulfonyl)-1-methyl-3-phenyl/1, 3-diphenyl/1-methyl-3- ethoxy propane-1, 3-dione(IVa-c) in corporating 4-methoxy benzene sulfonyl/ 4-methylthio benzene sulfonyl nucleus is described.Compounds IIIa-c and IVa-c were synthesize by the reaction of acetyl acetone/benzoyl acetone/ dibenzoylmethane/ethylacetoacetate(Ia-c & IIIa-c) with 4-methoxy benzene sulfonyl chloride 1 and 4-methylthio benzene sulfonyl chloride 2 in presence of sodium methoxide.Formation of 1 and 2 was achived by the reaction of anisol/thioanisole with chlorosulphonic acid.
