Our research on assembly line synthesis has been featured in a German magazine, Nachrichten aus der Chemie, in the section Synthese im Blickpunkt (Synthesis in Focus). Synthese im Blickpunkt wants to stimulate the use of new synthetic procedures or elegant and important organic syntheses. This year, contributions to the series are written by Johannes Teichert, Juniorprofessor in chemistry at the TU Berlin.

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!
