Amides are a class of easily available compounds, and widely serve as versatile intermediates in organic synthesis and medicinal chemistry. Amide-based transformations could lead to many useful compounds and intermediates including various amines, ketones and enaminones. Though direct transformation of amides is of high demand, many current chemoselective transformations are only achieved in multistep approaches. In recent years, direct transformation of amides is emerging as an exciting area. A number of recent progresses on nucleophilic addition to amide carbonyl group that led to new C—C bond formation are highlighted in this review, including (1) in situ amide activation with trifluoromethanesulfonic anhydride (Tf₂O) followed by addition of π- and σ-nucleophiles or reactive organometallic reagents; (2) direct transformation of N-alkoxyamides; (3) direct transformation of amides using Schwartz reagent; and (4) catalytic reductive C—C bond forming reactions of amides, and metal catalyzed coupling of amides.
Key words: amides, functional group transformation, one-pot reactions, synthetic methods, C—C bond formation
