Metal-Free Synthesis of 3-Arylquinolin-2-ones from<i>N</i>,2-Diaryl- acrylamides<i>via</i>Phenyliodine(III) Bis(2,2-dimethylpropanoate)- Mediated Direct Oxidative C−C Bond Formation
Treatment of N,2‐diarylacrylamides with the organoiodine(III) compound phenyliodine(III) bis(2,2‐dimethylpropanoate) [PhI(O2C‐t‐Bu)2] and boron trifluoride etherate (BF3⋅Et2O) resulted in a direct and selective oxidative C(sp2)−C(sp2) bond formation leading to a convenient assemblage, under mild conditions, of the biologically important 3‐arylquinolin‐2‐one skeleton. Differing from the five‐membered
Metal-Free Synthesis of 3-Arylquinolin-2-ones from Acrylic Amides via a Highly Regioselective 1,2-Aryl Migration: An Experimental and Computational Study
Combined experimental and theoretical investigations into the phenyliodine bis(trifluoroacetate) (PIFA)-mediatedreaction of N-arylcinnamamide to produce 3-arylquinolin-2-one derivatives have been conducted. High regioselectivity during the aryl migration process was observed in 3,3-disubstituted acrylamides. Density functional theory calculation was conducted in an attempt to understand the mechanism
