FIVE-MEMBERED 2,3-DIOXOHETEROCYCLES. XXXVII. REACTION OF 3-AROYL-1,2-DIHYDRO-4H-PYRROLOBENZOXAZINE-1,2,4-TRIONES WITH ALKYL- AND ARYLAMINES

3-Aroyl-1,2-dihydro-4H-pyrrolobenzoxazine-1,2,4-triones react with an equivalent amount of alkyl- and arylamines with the formation of N-substituted 3a-amino-3-aroyl-2-hydroxy-1,3a-dihydro-4H-pyrrolobenzoxazine-1,4-diones and N-substituted 4-aryl-2,4-dioxo-(Z)-3-(2-oxo-3,4-dihydro-2H-1,4-benzoxazin-3-ylidene)butyramides, which in the case of alkylamines exist as the ring isomers (Z)-3-(1-alkyl-5-aryl-5-hydroxy-2,3-dioxotetrahydro-4-pyrrolylidene)-3,4-dihydro-2H-1,4-benzoxazin-2-ones.An excess of the amine leads to the formation of (Z)-3-phenacylidene-3,4-dihydro-2H-1,4-benzoxazin-2-ones and substituted oxamides.
