我们报道了一个高对映选择性的,通用的催化体系,用于通过质子化邻近环酮的叔立构中心的简便合成。该方法依赖于容易获得的外消旋季β-酮酯的催化脱羧质子化。一系列取代的环烷酮化合物可以通过该方法以高水平的对映选择性获得。
We report a highly enantioselective, general catalytic system for the facile synthesis of tertiary stereocenters by protonation adjacent to cyclic ketones. The method relies on catalytic decarboxylative protonation of readily accessible racemic quaternary β-ketoesters. A range of substituted cycloalkanone compounds can be accessed through this process with high levels of enantioselectivity.
