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.
