Hydroxamic acid ester directed C(sp2)−H activation/annulation strategy has been reported employing electron-rich enamides under Ru(II)-catalysis to access aminal frameworks. Both N-vinyl acetamide and N-vinyl formamide delivered aminals bearing dihydroisoquinolinone motif in good yields. Under modified reaction conditions, vinyl acetate bestowed the selective formation of 3,4-unsubstituted isoquinolones. The protocol operates under mild conditions, where the C−H ruthenation step is reversible and apparently not the rate-determining step. © 2021 Wiley-VCH GmbH
