Chemoenzymatic resolution of β-azidophenylethanols by candida antarctica and their application for the synthesis of chiral benzotriazoles

The kinetic resolutions of (±)-β-azidophenylethanols were carried out using lipase from Candida antarctica, and enantiomerically enriched (R)-β-azidophenylethanols and their corresponding (S)-β-azidophenylethyl acetates were obtained in good enantiomeric excesses (up to > 99%). The enantiomerical...
