Studies on the enantioselective transformation of silacyclobutanes (SCBs) have become an emerging topic in the recent decade, due to the feature of high ring strain, and manageable Si–C bond cleavage and formation. This short review summarizes the remarkable achievements in the asymmetric transition-metal-mediated reaction of silacyclobutanes and benzosilacyclobutanes, resulting in carbon- or silicon-stereogenic organosilanes with functional substituents.
