Organo-photocatalysis

Results from our group has established the use of  stereoelectronic effects to manipulate excited state reactivity similar to ground state enantioselective transformations under organo-catalytic control. This opens up avenues to exploit the well-known stereoelectronic 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.
