An Efficient Lipase-Catalyzed Synthesis of Fatty Acid Derivatives of Vanillylamine with Antiherpetic Activity in Acyclovir-Resistant Strains
A series of eleven N-fatty acid derivatives of vanillylamine was synthesized following an enzymatic approach, in excellent yield and a chemoselective way. The excellent results obtained by catalysis of Thermomyces lanuginosus lipase made the procedure very efficient, considering the low amount of en...
