β-Amino-α-ketoamides 1 are a class of compounds exhibiting biological activity as reversible covalent enzyme inhibitors. The representative examples are clinically approved drugs for the treatment of hepatitis C virus Boceprevir 2 and Telaprevir 3. β-Amino-α- ketoamide substructure is also found in a number of natural products, many of which display a remarkable biological activity. The methods for the synthesis of β-amino-α-ketoamide can be classified based on the key steps of the synthetic routes: from unsaturated amide involving epoxydation followed by a regioselective azidolysis; from esters involving aminohydroxylation; from adehydes via Passerini reaction, cyanohydrin formation, addition of the masked acylcyanide (MAC) reagent or orthothioester; from imines via addition of dithiolane derived from oxoacetic acid, addition of isoxazolyl-4-triflates or via azetidinone formation; from acids via acylation of (cyanomethylene) triphenylphosphorane (the Wasserman procedure), via acylfurane formation or via Dakin-West reaction; from nitroalkanes via Henry reaction. In this review, the information from the scientific literature published within the period from 1990 till 2014 for the synthesis of β-amino-α-ketoamides is covered and systematized according to the above mentioned key steps. - See more at: http://eurekaselect.com/124000#sthash.EUO9P7nm.dpuf
