Unprotected, primary 2-azidoamines are versatile precursors to vicinal diamines, which are among the most common motifs in biologically active compounds. Herein, we report their operationally simple synthesis through an iron-catalyzed difunctionalization of alkenes. A wide array of alkene substrates are tolerated, including complex drug-like molecules and a tripeptide. Facile derivatizations of the azidoamine group demonstrate the versatility of this masked diamine motif in chemoselective, orthogonal transformations. Applications of the methodology in the concise synthesis of RO 20-1724 as well as in the formal total syntheses of both (±)-hamacanthin B and (±)-quinagolide further demonstrate the broad synthetic potential of this highly functional-group-tolerant reaction.

The invention discloses a novel method for synthesizing an N-substitute amide derivative. The novel method is characterized by comprising the steps that at the air atmosphere, no catalyst or alkali or other any additives are added, an organic amine compound shown in a formula (I) is adopted as a reaction substrate, a solvent shown in a formula (II) is adopted as an acylation reagent, an acylation reaction is performed under the reaction temperature of 120-150 DEG C to generate the N-substitute amide derivative shown in a formula (III), and the equation is shown in the description. The novel method has the advantages that environmental protection is achieved, and post-treatment and product separation are easy; the range of the substrate is wide, and the substrate can be primary amine and can also be secondary amine; the solvent can be amide and can also be carboxylic acid, and the solvent can be adopted as the acylation reagent to participate in the reaction; the reaction efficiency is high, and the majority of reactions can reach the quantified yield; water and air have no effect on the reaction, inert gas shielding is not needed, and operation is easy.
