2H-Pyran-2-ones with the defined (E)-structure of a α,β-didehydroamino acid unit were used as synthons for a series of configurationally stable (E)-α,β-didehydroamino acid derivatives containing a benzoyl protected amino function and a pyrazolyl residue. They were derived from 2H-pyran-2-ones and hydrazines under various reaction conditions. A possibility of the formation of (Z)-isomers from the above-mentioned precursors is also discussed.
