The stereoselective synthesis of anti isomers of gboryl-substituted homoallylic alcohols is disclosed. (E)-1,2-Di(boryl)alk-1-enes undergo Ru-catalyzed double-bond transposition with control of the geometry.T he in situ generated (E)-1,2-di(boryl)alk-2-enes add to aldehydes in astereospecific manner.T he alkenylboron group within the product is amenable to av ariety of synthetic derivatizations.

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.
