Abstract

The reactions of 3-acetyl-3-aza-11-oxatricyclo[6.2.1.0 1,6]undec-9-ene and its 9,10-epoxy derivative with bromine and Ac2O/BF3·OEt2 under different conditions were studied. Unusual products of Wagner-Meerwein rearrangement bearing the olefin fragment (5-aza-2-oxatricyclo[6.2.1.0 3,9]-undecen-3-enes) were isolated and characterized by X-ray analysis
