Roush asymmetric allylation
As first described by Hartwig, alkanes can be selectively borylated with high selectivity for the primary C–H bond using Cp*Rh(η -C6Me6) as the catalyst. Notably, selectivity for the primary C–H bond is exclusive even in the presence of heteroatoms in the carbon-hydrogen chain. The rhodium-catalyzed borylation of methyl C–H bonds occurs selectively without a dependence on the position … WebAn enantioselective asymmetric total synthesis of (+) ...
