Rhodium‐Catalyzed Spiro Indenyl Benzoxazine Synthesis via C‐H Activation/Annulation of 3‐Aryl‐2 H ‐Benzo[ b ][1,4]oxazines and Alkynes

Rhodium‐Catalyzed Spiro Indenyl Benzoxazine Synthesis via C‐H Activation/Annulation of 3‐Aryl‐2 H ‐Benzo[ b ][1,4]oxazines and Alkynes

The rhodium (III)‐catalyzed annulation of 3‐Aryl‐2 H ‐Benzo[ b ][1,4]oxazines with alkynes via C–H activation has been developed. This reaction afforded a series of spiro indenyl benzoxazine in high yields under mild reaction condition with good functional group tolerance.
