The asymmetric synthesis of a novel, C2-symmetric, tetradentate 1,10-phenanthroline is described; it is based on the stereoselective preparation of two functionalized pyridine subunits, which were subsequently joined through two consecutive carbon–carbon bond-forming reactions to assemble the heteroaromatic system. Some initial applications of this new chiral ligand in metal-catalyzed, enantioselective
描述了一种新型 C2 对称四齿 1,10-菲咯啉的不对称合成;它基于两个官能化吡啶亚单元的立体选择性制备,随后通过两个连续的碳-碳键形成反应连接起来组装杂芳族系统。介绍了这种新型手性配体在金属催化的内消旋环氧化物的对映选择性开环反应和 β-酮酯的胺化反应中的一些初步应用。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009 )
