Hydroxyiminoisoquinolin-3(2H)-ones. Part 4. Synthesis and Reactions of Isoquinoline-3,4-diones

Deoximation of the 4-hydroxyimino-1-phenyl-1,4-dihydroisoquinolin-3(2H)-ones (1), (2), and (3) with formaldehyde gave isoquinoline-3,4-diones; this reaction of the N-unsubstituted lactams (1) and (2) was found to be accompanied by hydroxymethylation of th
