It was established that the reaction of 3-aryl-1-(2-methyloxiran-2-yl)prop- 2-en-1-ones with tosylhydrazine leads to 3-[(E)-2-arylvinyl]-4-methyl-1-tosyl- 1H-pyrazoles and 3-aryl-1-(2-methyloxiran-2-yl)-3-tosylpropan-1-ones. The latter are formed as a result of rearrangement of the intermediate hydrazino alcohols and/or addition of p-toluenesulfinic acid during reductive degradation of the tosylhydrazine. It was shown that the reaction of 3-aryl-1-(2-methyloxiran-2-yl) -3-tosylpropan-1-ones with an excess of tosylhydrazine leads to 3-(2-aryl-2-tosylethyl)-4-methyl-1-tosyl-1H-pyrazoles. 2005 Springer Science+Business Media, Inc.
