copper‐catalyzed synthesis of dihydro[1,2‐b]indenoindole‐9‐ol and benzofuro[3,2‐b]indolines has been developed, whereby the same starting material is employed for the synthesis of both heterocyclic scaffolds and the selectivity of the product is controlled by switching the choice of metal. Salient features of these cascade reactions include wide‐ranging functional group tolerance, simple reaction conditions

A novel iodonium Truce-Smiles rearrangement featuring an aryl transfer from I to C pathway was developed, where no metal- or photo-catalysts are needed. The interaction between ionic liquids and diaryliodonium salts largely contributed to the efficiency of the reaction under mild conditions. This method furnished 64 examples of sulfonyl substituted ortho-iodo diarylmethanes as potentially valuable

An enantioselective intramolecular O-arylation was achieved through desymmetrization with Pd-catalyzed coupling reactions. The intramolecular asymmetric aryl C-O coupling reactions of 2-(2-haloaryl)propane-1,3-diols led to the enantioselective formation of chiral (3,4-dihydro-2H-chromen-3-yl)methanols in good yields and high enantiomeric selectivity.
