Intramolecular hydrogen shift of β-radical ketal was found in the reduction of optically active β-mercuro ketal. The addition of olefins to this hydrogen transferred radical proceeded regio and diastereo differentiatingly and afforded optically active sec-tert-1,3-diols.
发现β-自由基缩酮的分子内氢转移是光学活性β-汞缩酮的减少。将烯烃加到该氢转移的基团中,使区域和非对映体区别地进行,并提供了旋光的仲-叔-1,3-二醇。
