Abstract:The asymmetric transfer hydrogenation represents one important class of reactions for the synthesis of optically active compounds. A chiral ammonia borane was generated in situ from an H 2 release reaction between chiral phosphoric acid and ammonia borane, which could be regenerated by the assistance of water after the hydrogen transfer process and made this reaction catalytic. With this chiral ammonia borane, asymmetric transfer hydrogenations of β-enamine cyanides were realized to afford the desired products… Show more
This review provides an overview of the important progress in FLP-catalyzed asymmetric reactions made over the past 15 years, and both the merits and limitations of FLP-catalysis have been highlighted.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
