- Abstract
In this study, a series of enantioenriched sp3‐Ge/B bimetallic modules were successfully synthesized via an enantioselective copper‐catalyzed hydroboration of carbagermatrane (Ge)‐containing alkenes. Orthogonal cross‐coupling selectivity under different Pd‐catalyzed conditions was achieved in an enantiospecific manner. Notably, the chiral secondary Ge exhibited a remarkable transmetallation ability prior to primary or secondary Bpin. The effectiveness of this Ge/B bimetallic strategy was further demonstrated through the development of new functional small molecules with Aggregation‐Induced Emission (AIE) and Circularly Polarized Luminescence (CPL) performance. This represents the first successful example of synthesis of enantioenriched alkylgermanium reagents that permit enantiospecific cross‐coupling reactions.
