摘要：

o-(tert-Amino)benzamidoximes 6, N,N-disubstituted at the amid-N-atom of the nucleophilic moiety, are suitable neighbouring groups in cyclodehydrogenation reactions of tertiary amines using mercury(II)-edta. The kind of the N-substituents and the amount of oxidizing agent control the nature of the products, lactams 9 and anellated nitrones 8. The configuration of the tricyclic systems is determined by NMR spectroscopic methods. During the reaction an inversion of the configuration of the oxime moiety occurs, which is explained by an electrocyclic mechanism.
