Herein, we report a double deprotonation method used for the preparation of ynolates starting from nonbrominated 2,6-di-tert-butylphenyl esters. The current method is superior to the previously described double lithium/halogen exchange approach because easily accessible starting materials are used. This method will be especially useful for preparation of ynolates bearing functional groups in organic
在本文中,我们报道了一种双脱质子化方法,该方法用于从非溴代2,6-二叔丁基苯基酯开始制备ynolates。当前的方法优于先前描述的双重锂/卤素交换方法,因为使用了容易获得的原料。该方法对于制备有机合成中带有官能团的缩合物特别有用。
