VERSATILE AND STEREOSPECIFIC SYNTHESIS OF GAMMA,DELTA -UNSATURATED AMINO ACIDS BY WITTIG REACTION

摘要

The γ,δ-unsaturated α-amino acids of general formula (I). Also, a versatile process for the stereospecific synthesis of said compounds of formula (I), involving a Wittig reaction. Further, intermediate products of general formulae (II) and (III), as shown below, which are involved in the synthesis of compounds (I). Compounds of general formula (I) may be useful as therapeutic substances, or as reagents or intermediates for fine chemistry.
