catalysts that feature only a single stereogenic element, yet this minimal chirality resource is demonstrated to be competent for effecting high levels of stereoinduction in the asymmetric transfer hydrogenation over a broad range of ketone substrates, including those that are not accommodated by known catalyst systems. The single stereogenic center of the (1-pyridine-2-yl)methanamine) is the only point-chirality
该手稿描述了仅具有单个立体成因元素的Ru催化剂的设计和合成,但已证明这种最小的手性资源可在各种酮类底物(包括那些酮底物)上实现不对称转移加氢中的高水平立体诱导。不被已知的催化剂体系容纳。(1-吡啶-2-基)甲胺的单一立体异构中心是催化剂中唯一的手性点,相对于现有文献方案,这简化了该催化剂体系。
