Dz. Mijin et al., SYNTHESIS OF SUBSTITUTED 3-CYANO-2-PYRIDONES CATALYZED BY LIPASE FROMCANDIDA-CYLINDRACEA, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 33(3), 1994, pp. 309-311
Lipase from Candida cylindracea has been used to synthesize the substi
tuted 3-cyano-2-pyridones by cyclization of 1, 3-diketones with cyanoa
cetamide in water at 40-degrees-C. Synthesis has been performed in an
excess of cyanoacetamide and the products have been analyzed by IR and
H-1 NMR spectroscopy.
