synthetic points of view, the carbonylative transformation of NX bonds represents an interesting and attractive area of investigation. In light of this, the first carbonylative cross‐coupling between N‐chloroamines and organoboronic acids has been developed. This new type of aminocarbonylation proceeds at mild temperatures (45–55 °C) with 2 mol % Pd/C (10 wt %) as the ligand‐free catalyst. Not only arylboronic
A novel copper-catalyzed carbonylative cross-coupling between N-chloroamines and arylboronicsacids has been developed. With copper(I) oxide as the catalyst, various desired amide compounds were produced in moderate to good yields. Functionalgroups such as iodide and alkene are tolerated. Notably, this is the first example of a copper-catalyzed aminocarbonylation with N-chloroamines.

The synthesis of the alkaloid cryptopleurine 7b has been accomplished by a sequence involving as a key step the selective Borch reduction of an amidoester 1b to the corresponding aminoester 2b. This route is applicable to the synthesis of derivatives such as 7a.
