Herein we report a robust and synthetically useful catalyst-free amination methodology by the coupling of carboxylic acids and N-substituted formamides using POCl3 as a promoter. Versatile amides with a wide array of substituent groups were prepared within only 1 h in good to excellent yields. And even multi-substituted aromatic carboxylic acids could give the desired products with satisfactory results.

The invention relates to a method for synthesizing a phosphorus-oxychloride-promoted amide compound. The synthesizing method includes the steps that carboxylic acid serves as one reactant, another reactant (N,N-dialkyl methanamide) serves as a solvent, one equivalent of phosphorus oxychloride is added, and the amide compound is prepared. The reaction substrates are low in price and easy to get, the nature is stable, toxicity is small, the reaction speed is high, conditions are moderate, and the reaction substrates can be widely applied to substrates with different functional groups. The efficiently-constructed amide compound is an important molecular skeleton for many medicines, bioactive molecules and natural products, and the synthesizing method is a widely-applicable preparing method for synthesizing the compound.

The direct amidation of carboxylic acids with N-substituted formamides has been accomplished via ruthenium catalysis. In the presence of ruthenium catalyst, a versatile range of carboxylic acids and N-substituted formamides undergoes amidation reaction to produce synthetically useful amides in good yields. C[dbnd]O in amide product came from benzoic acid but not N-substituted formamides, and which was confirmed by Isotope experiment.

A direct amidation of carboxylic acids with tertiary amines could be carried out in the presence of the Ph3P-I2 activator. With an appropriate reagent addition sequence, a range of carboxylic acids including aliphatic, allylic, and aromatic acids could be converted into their corresponding tertiary amides under mild conditions without requirement of metal catalysis.
