A Ru(II)-catalyzed
directed C–H amination of 1,2,3-benzotriazinones
with azide compounds has been reported. The reaction has a wide substrate
scope of organic azides with good results and represents a useful
pathway to the construction of versatile heterocyclic amino products.
In addition, the method can be used for the phthalazinones, highlighting
the synthetic practicability of the strategy.
