In the presence of 1.5 mol% of [Rh(cod)(OH)]2, ring-opening reaction of benzocyclobutenols 36 proceed in a regioselective manner, allowing a two-step reaction involving a conjugation addition reaction of the thus-obtained Ar-Rh species with maleimides 45 and an aldol reacton with the resulting ketone group. The major products 52 consist of cis-fused 6-membered and 5-membered rings with the stereochemistry of hydroxyl group cis to the bridged head H-atoms, whereas the hydroxyl group is trans to bridged head H-atoms in the minor diastereomers 53. The intermediate 54, resulting from the initial conjugated addition of Ar-Rh to 45, was isolated as the minor product.銠金屬催化苯並環丁醇共軛加成馬來醯亞胺rhodium(I)-catalystedbenzocyclobutenolconjugate Additionmaleimide
