This review primarily focuses on the latest developments in Lewis acid-catalyzed strain-release cycloaddition reactions of BCBs.
This review aims to provide an overview on the recent visible light-mediated strain-release transformations of bicyclo[1.1.0]butanes. Prospects for future development of (aza)bicyclo[1.1.0]butanes in this fascinating field are outlined.
Bicyclo[1.1.0]butanes have beautiful conformations, distinctive properties, and novel reactivities. We summarize and highlight the recent advances of its photochemical strain-release reactions relying on SET or EnT strategies.
We present the first enantioselective dearomative (3+3) cycloadditions of bicyclobutanes (BCBs) utilizing a chiral Lewis acid catalyst and bidentate chelating BCB substrates.
Bicyclo[1.1.0]butanes have been utilized in a divergent Lewis acid catalytic platform to access various polycyclic architectures.
