Abstract

Since Miyaura reported the addition of aryl-and alkenylboronic acids to R, β-unsaturated ketones in an aqueous solvent under catalysis by a rhodium-phosphine complex in 1997, 1 this rhodium-catalyzed reaction has been successfully extended to catalytic asymmetric 1, 4- addition by use of binap as a chiral ligand. 2-5 Recently, it has been also reported that the reaction of arylboronic acids takes place with norbornene giving a multiple alkylation ...
