Moreover, R 1 and R 2 represent: a hydrogen atom; or either R 1 or R 2 represents a hydrogen atom and the other substituent is a radical R a , an acyl group —COR a , such as acetyl, or a functional group —COOR a , —SO 2 R a , —N (R a , R b ), R a and R b , which are identical or different, representing a C1-C12 linear or branched alkyl radical, optionally substituted, an aryl group with one or more aromatic rings and heterocycles, comprising between 5 and 8C, optionally substituted, or aralkyl, the alkyl substituent and the aryl group being as defined above; or R 1 and R 2 both represent a substituent as defined above. R 3 represents a hydrogen atom or R a and R 4 has the significance of R a . The invention is characterised in that it comprises: the isomerisation of a compound having formula (I), wherein R 1 , R 2 , R a , R 3 and R 4 are as defined above, such as to produce a compound having formula (II); and the reduction of the carbonyl function thereof which, depending on the catalytic system employed and the formula (I) compound used, produces one of the isomers having general formula (III) or (IV) or a mixture thereof having formula (B). The invention can be used for the synthesis of (2S, 3R, 4S)-4-hydroxyisoleucine.

    (2S,3R,4S)-4-Hydroxyisoleucine, which exhibits remarkable insulinotropic activity, is expected to be a potent drug to treat type II diabetes. We propose herein a four-step synthesis of the enantiopure natural product on the basis of successive Mannich condensation, catalytic epimerization, N-para-methoxyphenyl deprotection, and diastereoselective reduction. This compact economical and scalable sequence
