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。

hexafluoroisopropanol and the diazoalkane acts as an unreactive hydrogen‐bonding complex. Only after photoexcitation does this complex undergo a protonation‐substitution reaction to the reaction product. Investigations on the applicability of this photochemical transformation show that a broad variety of acidic alcohols can be subjected to this transformation and thus demonstrate the feasibility of
