Dehydrogenative Amide Synthesis: Azide as a Nitrogen Source
摘要:
A new atom-economical strategy to amide linkage from an azide and alcohol liberating hydrogen and nitrogen was developed with an in situ generated ruthenium catalytic system. The reaction has broad substrate generality including dials for the synthesis of cyclic imides.

A completely atom-economical and redox-neutral catalytic amide synthesis from an alcohol and a nitrite is realized. The amide C-N bond is efficiently formed between the nitrogen atom of nitrile and the alpha-carbon of alcohol, with the help of an N-heterocyclic carbene-based ruthenium catalyst, without a single by-product. A utility of the reaction was demonstrated by synthesizing C-13 or N-15 isotope-labeled amides without involvement of any separate reduction and oxidation step.
