Electrochemical Rearrangement of 3-Hydroxyoxindoles into Benzoxazinones

We report an unexpected rearrangement of 3-hydroxyoxindoles into benzoxazinones using electrochemistry. Our reaction employs mild and environmentally friendly conditions, and the benzoxazinone products are obtained in moderate to excellent yields. Mechanistic experiments suggest that a peroxide intermediate is likely involved.

Friedel-Crafts Acylation with 2-Isocyanatobenzoyl Chlorides: The Structure of the Intermediate Complex

The intermediate complex obtained in the Friedel-Crafts acylation of benzene with 2-isocyanatobenzoyl chloride (1a) reacts with methanol or ethanol in the presence of ether affording 4-alkoxy-4-phenyl-1,4-dihydro-3,1-benzoxazin-2(1H)-ones, whereas with anilines, the corresponding anils of 2-aminobenzophenone are obtained.In the presence of triethylamine, the complex reacts with aniline and 2-aminobenzophenone affording 4-hydroxy-4-phenyl-3-substituted 3,4-dihydroquinazolin-2(1H)-ones whereas, with alkyl anthranilates, the new 11b-phenyl-7,11b-dihydroquinazolinobenzoxazine-6,13-diones are obtained.Similar products are also obtained from 5-chloro-2-isocyanatobenzoyl chloride.The intermediate complex has been shown to exist exclusively in the cyclic form in both acidic and basic media.
