An electrochemical method for the synthesis of carboxylic as well as hindered esters from N-alkoxyamides has been reported. The electrochemical reaction proceeds through constant current electrolysis (CCE) by taking advantage of the dual role of n-Bu4NI (TBAI) as the redox catalyst as well as the supporting electrolyte. Besides providing mild reaction conditions, the present protocol is free from external

Diselenoacetals, previously considered byproducts in homologation tactics en route to α-selenoketones, are herein found to be excellent starting materials for this purpose. The easy selenium/lithium exchange they undergo affords seleno carbanions which are smoothly added to Weinreb amides to chemoselectively prepare α-aryl- and α-alkyl seleno methylketones through a single chemical operation. No racemization
Inspired by recent transition-metal catalyzed electrophilic amidations, we developed a photo-induced electrophilic amidation of arylboronic acids with Fe catalyst to construct C−N bond. This protocol is also featured by its mild condition and broad substrate scope.
受最近过渡金属催化的亲电酰胺化的启发,我们开发了芳基硼酸与 Fe 催化剂的光诱导亲电酰胺化以构建 C-N 键。该协议还具有条件温和、底物范围广的特点。
