Practical Resolution of 3-Phenyl-2H-azirine-2-methanol at Very Low Temperature by Using Lipase Immobilized on Porous Ceramic and Optimized Acylating Agent

A synthetically useful primary alcohol, 3-phenyl-2H-azirine-2-methanol, was resolved efficiently by a reaction at -40 °C with a lipase immobilized on the porous ceramic (Toyonite) and vinyl butanoate in ether (E value of 130 and TTN/h value of 7800).
