A conceptually novel biomimetic strategy based on a domino amination-oxygenation reaction was developed for direct amidation of aldehydes under metal-free conditions employing molecular oxygen as the oxidant. 9-Aminofluorene derivatives acted as pyridoxamine-5′-phosphate equivalents for efficient, chemoselective, and operationally simple amine-transfer oxygenation reaction. Unprecedented RNH transfer involving secondary amine to produce secondary amides was achieved. In the presence of 18O2, 18O-amide was formed with excellent (95%) isotopic purity.

A novel catalytic method for synthesizing 4-aryl-2-quinolinones is reported. The process involves two mechanistically independent, sequential Pd(ii)-catalyzed reactions - the oxidative Heck reaction and the intramolecular C-H amidation - both of which smoothly proceed in the presence of a single catalytic system in a one-pot manner.

Radical cyclizations of conjugated esters and amides with 3-oxopropanenitriles mediated by manganese(III) acetate

Radical cyclizations of conjugated esters and amides with 3-oxopropanenitriles in presence of manganese(III) acetate produced ethyl 4-cyano-2,3-dihydrofuran-3-carboxylates and 4-cyano-2,3-dihydrofuran-3- carboxamides in good yields. The radical cyclizations of conjugated amides gave 2,3-dihydrofurans in better yields than that of conjugated esters. Moreover, the reactions of thienyl substituted amides and esters with 3-oxopropanenitriles afforded 2,3-dihydrofurans more efficiently than phenyl substituted ones. ARKAT-USA, Inc.
