With the optimal electrocatalysis conditions in hand, we next investigated the scope of the cobaltaelectro-catalyzed atroposelective C-H annulation (Scheme 3). A wide range of benzamides with varying electronic properties furnished the corresponding C-N axially chiral isoquinolinones (4-19) affording the desired products with high yields and excellent enantioselectivities of 96 to >99% ee. This cobalta-electrocatalysis was well compatible with diverse functional groups including electrophilic cyanide and ester substituents (9, 10). For meta-substituted benzamides, it was found that the reactions occurred mainly on the less hindered ortho-position, delivering the target products 12 and 13 in good yields with high enantioselectivities. 2,3-Disubstition with electrondonating methoxy groups on the benzamide was also well tolerated and product 14 could be isolated in 85% yield with 99% ee.
