Lipophilic (Hydroxy)phenylacetates by Solvent-Free Lipase-Catalyzed Esterification and Transesterification in Vacuo

Various long-chain alkyl (hydroxy)phenylacetates were prepared in high yield by lipase-catalyzed transesterification of the corresponding short-chain alkyl hydroxyphenylacetates and fatty alcohols in equimolar ratios. The reactions were performed in vacuo at moderate temperatures in the absence of s...
