polyethyleneoxy chain on the ligand (i.e. the regulation site) via supramolecular interactions. This approach has been applied to an array of structurally diverse alcohols (cycloalkyl, alkyl and aryl derivatives). Moreover, we have used this methodology to synthesise advanced synthetic intermediates of biologicallyrelevant compounds.

Keeping it organic: A direct synthesis of α‐alkoxy and α‐amino ester derivatives by direct reductive coupling of widely available, stable α‐keto esters and protic pronucleophiles is described (see scheme; X=OR, NR2). The method serves as a convenient nonmetal alternative to XHinsertion by diazo decomposition.
使其保持有机状态:已描述了通过广泛可得的,稳定的α-酮酸酯和质子性亲核试剂的直接还原偶联直接合成α-烷氧基和α-氨基酯衍生物的方法(参见方案; X = OR,NR 2)。该方法可作为重氮分解中XH插入的便捷非金属替代方法。
