Synthesis of derivatives of Sulfonyl acyl hydrazine under solvent free condition

Acyl hydrazides constitute very important moieties in organic chemistry and have been employed asstarting materials for different transformations to many classes of organic compounds. In the present paper, wedescribe the synthesis of novel derivatives prepared by regioselective Michael addition to asymmetric hydrazidecompounds. This chemoselectivity was experimentally studied employing different reaction conditions.Asymmetric hydrazide was synthesized via green chemistry approach.at the first acyl hydrazide was synthesizedby using methyl benzoate and hydrazine hydrate. In the next step, mixture was reacted with the sulfonylderivatives. finally finish, sulfonylacyl hydrazine was synthesized reacted with acrylates via regioselectiveMichael addition.
