Solid-phase synthesis of amino acid derived N-unsubstituted pyrazoles via sydnones

A new method to synthesize N-unsubstituted pyrazoles on a solid support is described. The solid support acts as a protecting group for the amino acid. N-Protected amino acid is N-nitrosated, and the subsequent treatment with acetic anhydride in a microwav
