A palladium-catalyzed reaction of 2-alkynylbromobenzene with 2-(2-alkynyl)benzenesulfonamide has been developed, which gives rise to 6H-benzo[f]indeno[1,2-d][1,2]thiazepine 5,5-dioxides in good yields.
unprecedented (SiMOS-Phos) ligand-controlled Rh-catalyzed hydrosilylation of “silicon-centered” racemic hydrosilanes was developed for the highly efficient and enantioselective construction of silicon-stereogenic centers of benzosiloles (up to 96 : 4 er). This achievement was obtained by using an original synthetic strategy involving dynamic kinetic asymmetric transformations.
