The chiral amide-guanidine-catalyzed asymmetric formal [3+2] cycloaddition of isatogens with azlactones is presented. This strategy provided a facile and feasible route to chiral indolin-3-one derivatives bearing two contiguous tetrasubstituted stereocent

Using a bulky electron-rich monodentate benzoferrocenyl phosphine as supporting ligand, an efficient protocol for stereoselective palladium-catalyzed Suzuki-Miyaura cross-coupling of aryl chlorides with alkenylboronic acids was uncovered. Using this protocol, both trans- and cis-alkenylboronic acids can be coupled with high stereoselectivity giving the corresponding vinylarenes in good to quantitative yields. Electron-poor and -rich aryl chlorides including highly hindered ones are all suitable substrates for the reaction.
