N-(4-(piperidin-1-yl)pyridin-2-yl)amide derivatives as potential stereoselective catalysts. The key intermediate, 2-amino-4-piperidinyl pyridine, was obtained by nucleophilic substitution of 2-amino-4-chloropyridine with piperidine in good yields (up to 96%). The total control of enantioselectivity was obtained for the synthesis of L-proline and (R)-1,1′-bi(2-naphthol) derivatives. GRAPHICAL ABSTRACT
摘要 已开发出一种简便的方法来提供一系列新型手性 N-(4-(哌啶-1-基)吡啶-2-基)酰胺衍生物作为潜在的立体选择性催化剂。关键中间体2-氨基-4-哌啶基吡啶是通过2-氨基-4-氯吡啶与哌啶的亲核取代获得的,产率高达96%。L-脯氨酸和(R)-1,1'-双(2-萘酚)衍生物的合成获得了对映选择性的完全控制。图形概要
