  摘要：

  The behavior of epoxides of linalool and cis-nerolidyl acetate was comparatively investigated in acids of various strength with the goal of establishing the effect of the structure of the initial c compound and the medium character on the main direction of cationoid rearranuement. Linalool epoxidcS undergo cyclization, of solid acid catalysts affording oxygen-containing heterocyclic Compounds whereas the nerolidyl acetate epoxides yield the ketones originating from the opening of the epoxy ring followed by 1,2-hydride shift. 10,11-Epoxy derivative of cis-nerolidyl acetate affords 7-oxanorbornane as a minor product.
