It could be used to make many kinds of drugs or compounds -- and almost any molecule that involves an asymmetric reaction.
The approach highlights asymmetric reactions for the formation of functional groups through the formation of carbon-heteroelement bonds, paying special attention to reactions that are highly selective but also to those that show the largest substrate scope.
The sources of the asymmetric reactions remain a puzzle, which may warrant additional research.
