Hybrid density functionals and ab initio studies of 2-pyridone–H2O and 2-pyridone–(H2O)2
Chemical Physics Letters, 2000Abstract Theoretical calculations have been carried out on the interaction between water and the carbonyl base 2-pyridone. The calculations have been performed with two hybrid density functionals (B3-PW91 and B3-LYP). The comparison with experimental gas phase data as well as with results from the ab initio methods RHF and MP2 shows good performance ...

Enantioselective Photochemical Reactions of 2-Pyridones in Solution
Organic Letters, 2001[reaction: see text] Two key photochemical reactions of prochiral 2-pyridones were studied in the presence of a chiral host. The [4 + 4]-photocycloaddition with cyclopentadiene (CpH) proceeded smoothly and with high enantioselectivity (84-87% ee). The absolute configuration of the endo-diastereoisomer was established by X-ray crystallography.

The photoreactions of N-methyl-2-pyridone
1970In studying the photochemistry of N-methyl-2- pyridone, four products were observed. Besides the previously known dimer and bicyclic monomer, two new dimers were isolated. The quantum yields of product formation were measured, and it was found that only one intermediate was involved.
