Single-crystal X-ray structures of 6 carboxamides possessing two units of 2-pyridone moieties connected with an iminodicarbonyl linker were examined to show the usefulness of this linker for the creation of concave-shaped conformation in crystal structure

Ester hydrolysis studies on some isomeric methoxycarbonyl derivatives of N-methylpyridin-2- and 4-ones show that reaction rates are affected by the relative positions of CO2Me, =O and NMe functions in ways which could not be predicted.However, from limited results for analogous pyrimidine derivatives, it seems that reactivity in these polyfunctional compounds can be predicted from the pyridine data by assuming additivity of effects.
A 'Biogenetic Like' Synthesis of Perloline, 6-(3,4-dimethoxyphenyl)-5-hydroxy-5,6-dihydrobenzonaphthyridin-4(3H)-one

9H-Indenopyridine-1(2H),9-dione, prepared by a new efficient route, reacts with 3,4-dimethoxyphenyllithium to form the keto alcohol (7), which rearranges with hydrazoic acid to form 5-(3,4-dimethoxyphenyl)benznaphthyridin-4(3H)-one.The N-oxide photolyses smoothly to yield dehydroperloline as the sole product.
