摘要：

The reactions of 1-amino-2-nitroguanidine with 3-nitroacrylates afford aza-Michael adducts. The latter when refluxed in an aqueous alkaline medium undergo elimination of nitrous acid followed by shift of the resulting C=C bond into C=N position giving finally N -substituted alkylpyruvate hydrazones. These compounds can also be prepared in a one -pot procedure; NMR spectroscopy and X-ray diffraction analysis confirmed the existence of the obtained hydrazones as E -isomers.
