Lipase-Catalyzed Solvent-Free Amidation of Phenolic Acids [PDF]

open access: yesSynthetic Communications, 2014
A series of N-alkyl-substituted amides, based on various phenolic acids, have been synthesized by the condensation of equimolar amounts of phenolic acids with different alkyl amines in the presence of Candida antarctica lipase at 60–90 °C in 16–20 h. The reactions were carried out in a solvent-free system without the use of any activating agents.
