A new and improved method for the synthesis of glycolylhydroxamic acids is described. The two-step method involves acylation of arylhydroxylamines with acetoxyacetyl chloride, followed by saponification of the ester bond to give the desired products. The conversion of hydroxamic acids

The facile synthesis of the stabilized axial and equatorial conformers of spiro-β-lactams was achieved via entrapment of cyclohexanone imines (Schiff bases) with acetoxyacetyl chloride in a [2 + 2]-cycloaddition reaction followed by their kinetic resolution. The immobilization of the racemic
