A short six-step synthesis of (2S,3R,4S)-4-hydroxyisoleucine (1a) with total control of stereochemistry is reported, the last step being the enzymatic resolution by hydrolysis of a N-phenylacetyl lactone derivative using the commercially available penicillin acylase G immobilized on Eupergit C (E-PAC).
