PRACTICAL SYNTHESIS OF OPTICALLY ACTIVE α-HYDRAZINO ACIDS FROM α-AMINO ACIDS
Viret, Joelle,Gabard, Jacqueline,Collet, Andre
, p. 891 - 894 (1987)
Simple amino acids (1) can be converted in fair to good yield into hydrazino acids (3) of like configuration by using KOCl instead of NaOCl to promote the Shestakov rearrangement of the intermediate hydantoic acids (2).
