stereoselective reaction has been accomplished in the presence of malonates, 1,3-ketoesters, and 1,3-diketones with good to excellent yields under mild conditions. This methodology represents the first allylation of 1,3-dicarbonyl compounds with allenes catalyzed by copper.
发现简单的无配体的铜体系是将1,3-二羰基化合物加至N-烯基衍生物的有效催化剂。在丙二酸酯,1,3-酮酸酯和1,3-二酮的存在下,已经在温和条件下以良好或优异的产率完成了这种高度区域选择性和立体选择性的反应。该方法学代表1,3-二羰基化合物与铜催化的丙二烯的第一次烯丙基化。
