A variety of arylated anthraquinones were prepared by site-selective Suzuki-Miyaura cross-coupling reactions of the bis- and tris(triflates) of alizarin and purpurin, respectively. The site-selectivity is controlled by the electronic influence of the carb

We have determined that a cationic rhodium(I)/Segphos complex catalyzes an enantio- and diastereoselective intermolecular [2 + 2 + 2] cycloaddition of 1,2-bis(arylpropiolyl)benzenes with various monoalkynes at room temperature to give axially chiral 1,4-t
