An unusual new reaction of Cp2ZrHCl transforms β-ketoesters into α,β-unsaturated esters in one step and provides a useful alternative to the traditional, three-step process of reduction, mesylation/tosylation, and elimination.
Cp 2 ZrHCl的一个不寻常的新反应可以一步将β-酮酸酯转变为α,β-不饱和酯,并为传统的三步还原,甲磺酸化/甲苯磺酸化和消除过程提供了有用的替代方法。
