Abstract:

The Acylase "Amano" (AA)-catalyzed synthesis of valuable pyridin-2-ones via domino Knoevenagel condensation-Michael addition-intramolecular cyclization-oxidization reaction between aldehyde, cyanoacetamide and ethyl acetoacetate or cyclohexyl acetoacetate was developed in the sense of a one-pot strategy. Various aliphatic, aromatic and hetero-aromatic pyridin-2-ones could also be produced in the reaction. The mechanism was illustrated according to the controlled reaction, pyridin-2-one was formed via the oxidization by oxygen at the final step. This simple and efficient enzymatic domino reaction not only widens its application of AA to organic synthesis, but is also an attractive way for the synthesis of heterocyclic compounds.
