Abstract
The reactions of N,N-dioxyenamines with carboxylic and sulfonic acid anhydrides were investigated. A new method for the synthesis of α-hydroxyoxime derivatives via the reaction of N,N-dioxyenamines with trifluoroacetic anhydride is described.
Key words
1,2-oxazine - trifluoroacetic anhydride - hydroxyoxime - enamine - rearrangement
