Iridium/chiral diene-catalyzed asymmetric 1,6-addition of arylboroxines to alpha,beta,gamma,delta-unsaturated carbonyl compounds.
Iridium-catalyzed asymmetric 1,6-addition of arylboroxines to alpha,beta,gamma,delta-unsaturated carbonyl compounds to give delta-arylated carbonyl compounds in high yields with 90-99% enantioselectivity was realized by use of an iridium/chiral diene complex.
