A variety of opticallyactive β-allenols and β-allenyl acetates were synthesized via the Novozym 435-mediated kineticresolution of racemic β-allenols. A dramatic solvent effect was observed for the stereoselectivity. The scope of the substrates and the effect of the concentration and temperature on the reaction were also investigated.
