The reaction of ketene-iminium ions with various olefins: A new preparation method for grandisol, fragranol and related dimethyl ethers

We describe here the preparation of grandisol, fragranol and several related cyclobutanic by-products by procedures employing a [2+2] cycloaddition reaction between an olefine and a ketene-iminium cation generated in situ from an α-chloroenamine. The region- and stereospecificity of these cyclization reactions are studied.
