,Copper-Catalyzed α-Amination of Phosphonates and Phosphine Oxides: A Direct Approach to α-Amino Phote zincates with .-acyl hydroxylamines. This amination provides the first example of C–N bond formation which directly introduces acyclic and cyclic amines to the α-position of phosphonates in one step. The reaction also demonstrates high efficiency on a broad phosphonate substrate scope.摄取 发表于 2025-3-25 15:39:19

,Selective α-Amination and α-Acylation of Esters and Amides via Dual Reactivity of ,-Acylhydroxylamily relevant molecules. Selective α-amination and α-acylation of esters and amides have been developed, employing .-acylhydroxylamines as a dually reactive aminating and acylating reagent. Treatment of zinc enolates with .-acylhydroxylamines provides solely 1,3-dicarbonyl compounds under mild conditi惊呼 发表于 2025-3-25 22:17:11

,Copper-Catalyzed Electrophilic Amination of Heteroarenes and Arenes by C–H Zincation,for the synthesis of these important heteroaryl amines are highly valuable. Direct amination of heteroarenes and arenes has been achieved in a one-pot C–H zincation/copper-catalyzed electrophilic amination procedure. This amination method provides an efficient and rapid approach to access a diverse和音 发表于 2025-3-26 06:14:46

The Role of Sulfur in Plant Abiotic Stress Tolerance: Molecular Interactions and Defense Mechanisms,e S uptake, translocation, and mechanisms of action in plants under stressful conditions are still under research. The recent progress on the roles of S in conferring abiotic stresses and related literature is presented in this chapter.
