towards construction of amide C–N bonds under mild conditions through rhodium(III) catalysis has been explored. Previous waste-free amidations were generally limited to the condensation of carboxylic acids and amines. In this report, we directly applied amination of the aldehyde C(sp2)–H bond to extend the scope of amidation reactions. The amination shows a wide substratesscope, and several important

A Cu0‐catalyzed protocol is proposed for the synthesis of 8‐acylquinolines through a [3+2+1] annulation starting from anthranils and phenylacetaldehydes. This protocol is of particular interest in preparing 8‐aldehyde quinolines, which have been hard to access so far. Both AgOTf and dioxygen played an important role in the reaction. C3‐heterocycle or phenylethylene substituted anthranils could also
