Abstract
2H-Pyran-2-one derivative (1) was transformed with heterocyclic hydrazines and 2,4-dinitrophenylhydrazine, under the influence of various acidic catalysts, into N-[5-(1-hydrazonoethyl)-6-methyl-2-oxo-2H-pyran-3-yl]benzamides (3) as the main products, accompanied in some cases by the corresponding (E)-α,β-didchydro-a-amino acid derivatives (4).
