The activation of carbon-carbon bonds has attracted much attention in the past decade. Despite important progress, the development of asymmetric reactions lags behind. For the first time, asymmetric rhodium(I)-catalyzed direct oxidative additions into enantiotopic C-C bonds of cyclobutanones could be realized. Subsequent carboacylation of tethered olefins and carbonyl groups of the generated rhoda(III)cyclopentanone
在过去的十年中,碳-碳键的激活引起了广泛的关注。尽管取得了重要进展,但不对称反应的发展仍然落后。第一次,可以实现不对称铑(I)催化的环丁酮对映体CC键的直接氧化加成。系留的烯烃和所生成的Rhoda(III)环戊酮的羰基的后续碳酰化可有效地以高收率获得复杂的多环支架。尽管在高反应温度下进行操作,但是该方法的特征在于通常大于99.5:0.5 er的突出的对映选择性。
