Normally many lipases are efficient catalysts for the acetylation of alcohols with vinyl acetate. Unexpectedly, we found that some sterically hindered secondary alcohols react slowly to yield hemiacetal esters as mixtures of diastereomers. Their formation can be explained by the reaction of the alco
