A new strategy that employs an exocyclic stereocenter to effect diastereocontrol in the tetheredaminohydroxylation (TA) reaction is applied to the stereoselective synthesis of a range of amino alcohols in good to excellent yields, and with anti selectivities of up to 20:1. The influence of the reaction conditions and substrate parameters on the level of diastereocontrol is described. Furthermore,

A novel approach for the preparation of chiral α-quaternary isochromanes is reported by combining enantioselective oxidative aminocatalysis and goldcatalysis. The presented isochromanes can be applied to scaffold derivatization and photoaffinity labelling of proteins.
