Results from our group has established the use of stereoelectronic effects to manipulate excited state reactivity similar to ground state enantioselective transformations under organo-cataytic control. This opens up avenues to exploit the well-known streoelectronic effects to control reactivity and selectivity for some of the most synthetically useful excited state transformations. Some of the recent publication from our group is listed below.
