ring, transesterification of the phosphonate group occurs, accompanied by the destruction of P–C bond. The ester group is transesterified in any case. The resulting alcohols are oxidized by the dimethyl sulfoxide–acetic anhydride system or by the complex of chromium trioxide with pyridine to the corresponding aldehydes. The P–C bond is not affected in this case. The resulting aldoketones react with hydrazine
