1,4-Addition of arylboronic acids to β-aryl-α,β-unsaturated ketones and esters catalyzed by a rhodium(I)–chiraphos complex for catalytic and enantioselective synthesis of selective endothelin A receptor antagonists
An enantioselective synthesis of acyclic β-diaryl ketones and esters via 1,4-addition of arylboronic acids to β-aryl-α,β-unsaturatedketones or esters is described. The complex in situ prepared from [Rh(nbd)2]BF4 and chiraphos was found to be an excellent catalyst to achieve high enantioselectivities in a range of 83–89% ee for the ketone derivatives and 78–94% ee for tert-butyl β-arylacrylate derivatives

A previously described mixture of bicyclo[4.4.0]decanecarbonitriles [(4) and (5)] was converted, via a nine-step sequence of reactions, into (±)-isolinaridiol (3), which was readily transformed into the corresponding diacetate (2).
