Excellent stereoselectivity is obtained in the synthesis of biologically interesting 1,2,3‐trisubstituted indanes B by the reaction of readily prepared 3‐substituted indenes A with commercially available arylboronicacids by using various TEMPO derivatives as external oxidants and Pd(OAc)2 as a catalyst. The anti,anti isomers are formed and reactions occur stereospecifically under mild conditions.
