Iminofuran chemistry: I. Decyclization of N-substituted 5-aryl-3-imino-3H-furan-2-ones by the action of OH-and NH-nucleophiles

In reactions of N-substituted 5-aryl-3-imino-3 H -furan-2-ones with OH-and NH-nucleophiles the nucleophilic reagents attack the carbon atom in the position 2 of the furan ring. All reactions involve the destruction of the furan system.
