Rh( iii )-catalyzed annulation of N-methoxybenzamides with ynesulfonamides at room temperature: a practical and efficient route to 4-aminoisoquinolone derivatives

A mild Rh( iii )-catalyzed annulation of N -methoxybenzamides with ynesulfonamides has been developed for the synthesis of 4-aminoisoquinolone derivatives under external-oxidant-free conditions.
