Abstract
Treatment of the ozonization products from N-acetyl- or 2-methyl-N-trifluoroacetyl-6-(cyclopent-1-enyl)anilines with NaBH4 gives 6-methyl-2-tetrahydropyranylaniline. When treated with Me2S, the ozonization products yield the corresponding oxoaldehyde dimethyl acetals. The oxidation of N-acetyl-2-(cyclopent-1-enyl)- or -(cyclohex-1-enyl)anilines with H2O2 in HCOOH affords ω-(2-acetamidophenyl)-5-oxopentanoic or -6-oxohexanoic acid, respectively. The reaction of N-acetyl-2-(cyclopent-1-enyl)aniline with H2O2 in the presence of Na2WO4 and H3PO4 gives 3,1-benzooxazine in high yield.
