Abstract (S)-(E)-(+)-1-Bromo-1-octene-3-ol was prepared in 85% yield and high optical purity (ee 97.4%) via a stereospecific reduction of corresponding bromo vinyl ketone using alcohol dehydrogenase from baker's yeast (EC 1.1. 1.1) and NAD (P) H immobilized on Nucleosil 120-5 C 18, and converted to 13 (S)-hydroxy-9Z, 11E-octadecadienoic (coriolic) acid.
