The iterative lithiation-borylation combines C-C bond formation with the selective construction of asymmetrically substituted carbon atoms. This methodology allows to build adjacent stereocentres in rapid succession.
The stereoselective lithiation-borylation is a good tool to generate alkyl chains with stereogenic centres. Particularly attractive is that different building blocks are obtained in a reaction sequence and simultaneously C-C bonds and stereocentres are generated. Such reactions occur in good yields and with high stereoselectivity, which compromises the stoichiometric use of metal reagents and chiral ligands as sparteine.
Dr. Chao Shu has joined our lab as a postdoctoral researcher. Welcome to the group, Chao!
Dr. Hannah Baars has finished her postdoctoral studies in our lab and moved back to Germany. All the best, Hannah!
