Enantioselective Conjugate Arylation of Coumarins

Conjugate Arylation of Chiral, Racemic o,p-Unsaturated Carbonyl Compounds 

Conjugate Asymmetric Arylation of 3-Substituted a,P-unsaturated Carbonyl Compounds 

6- Addition of Arylboronic Adds to a,p,y,5-Unsaturated Carbonyl Compounds 

Recent approaches by Hayashi and others aimed at expanding the arylation chemistry to include also a,p,y,5-unsaturated carbonyl compounds as acceptors. In this vein, enynones such as 126 undergo a rhodium-Segphos (50)-catalyzed 

In a recent report by Csiky, 2,4-dienoate esters 130 were employed as electro-phihc partners for a rhodium] I)-catalyzed regioselective 1,6-addition of arylboronic
