Next, the scope of gem-borazirconocene alkanes was evaluated (Figure ). The asymmetric catalysis exhibited insensitivity to the chain length of gem-borazirconocene alkanes (3a, 4b-c). A wide range of functional groups such as alkyl chloro (4d), silane (4g), ether (4k), sulfonamide (4i), and indole (4j) were well-tolerated. The reactivity and enantioselectivity of the reaction were influenced by the steric hindrance of gem-borazirconocene alkanes. The bulky substrates (4e, 4f, 4g, 4l) gave lower yields and enantioselectivity, as evidenced by the comparison between 4h and 4l. The protocol could also be applied to several bioactive molecules including glucose (4m), cholesterol (4o), and DL-alpha-Tocopherol (4n), highlighting the high functional-group tolerance of the method. By harnessing the Bpin directed "chainwalking" effect, the general terminal or internal alkenes can be converted into gem-borazirconocene alkanes to realize remote C-H functionalization . The terminal alkene substrates (4p, 4q) were successfully transformed into gem-borazirconocene alkanes and performed excellently in the decarboxylative cross-coupling with high enantioselectivity, further demonstrating the broad substrate scope of this method.
