2-fused oxindoles from methyl ketones and anilines. This approach was optimized, resulting in a concise and atom-economical approach for the one-pot construction of 1,2-fused oxindoles from methyl ketones and anilines rather than using preexisting indolin-3-ones or indoles. Mechanistic studies revealed that the key step involved an oxidativecross-couplingbetween in situ generated phenylglyoxal and α

with bases have been systematically examined. Monomeric C-methoxy-imines are available fromsome of these reactions. C-methoxyphenacylarylamines, made by two routes, were converted into monomeric imines on treatment with noble-metal catalysts. The boron trifluoridecatalysed reactions of aryl aldehydes with sulphonamides provide a new and convenient route to N-sulphonylarylimines.
