Abstract
A novel method for the production of natural aromatic ester compounds such as methyl anthranilate, ethyl anthranilate butyl anthranilate methyl cinnamate and methyl salicylate comprises the esterification of their corresponding acids using microbially derived enzymes in the presence of a C.sub.1 -C.sub.4 alcohol such as methanol, ethanol or butanol. A biphasic reaction medium may optionally be utilized to generate maximum yields through the addition of a non-polar organic solvent such as hexane, ethyl acetate, heptane and the like.
