摘要
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 alpha-chloroenamine. The regio- and stereospecificity of these cyclization reactions are studied.
