A novel method for the synthesis of chiral alpha-amino acids has been developed where the acid functionality was constructed by oxidizing a hydroxymethyl group introduced by Evans' method in the alpha-position of an appropriate acid substrate and the amino part came from the amide of the original carboxyl group following a modified Hofmann rearrangement reaction.

It relates to polymyxin analogues having a disulfide bond and an amino alcohol group adjacent to the disulfide bond, and optionally, an ester bond in the peptide backbone, which are useful as antibacterial agent, as well as to pharmaceutical compositions comprising them. It also relates to a key intermediate compound of formula (II) and its preparation process.
