The reaction of β,γ-unsaturated esters and nitriles with camphor diselenide and ammonium persulfate in methanol, ethylene glycol or water affords enantiomerically enriched γ-alkoxy or γ-hydroxy α,β-unsaturated derivatives, respectively, in good chemical yields and with moderate to good enantioselectivity.
β,γ-不饱和酯和腈与樟脑二硒化物和过硫酸铵在甲醇,乙二醇或水中的反应分别得到对映体富集的γ-烷氧基或γ-羟基α,β-不饱和衍生物,化学收率良好,温和良好的对映选择性。
