the straightforward reductive opening of 1,2 epoxides to alcohols was studied and applied to several significant compounds. The reaction, which proceeds via the nucleophilic opening of the oxirane ring and the subsequent free radical dehalogenation, shows an excellent chemical yield as well as chemo and regioselectivity. This reaction was also applied to a chiral α,β-epoxyester.
研究了将1,2环氧化合物直接还原成醇的方法,并将其应用于几种重要的化合物。该反应通过环氧乙烷环的亲核开口进行,随后发生自由基脱卤反应,显示出优异的化学收率以及化学和区域选择性。该反应也适用于手性α,β-环氧酯。
