We propose one-pot synthesis of siloles from readily available
starting materials. This methodology is practical for the preparation
of multisubstituted siloles in good to excellent yields with complete
regioselectivity. Sequential reactions, such as lithiation, silylation,
and diisobutylaluminum-hydride-promoted cyclization, enable the preparation
of the siloles. This transformation provides siloles through two efficient
C–Si bond formations in one vessel.
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.
