Palladium-Catalyzed Cross-Couplings of 2-Tributylstannyl-N-Boc-2,3- Dehydropiperidine, a Cyclic Enecarbamate

Cross-couplings of 2-tributylstannyl-N-Boc-2,3-dehydropiperidine, a six-membered cyclic enecarbamate, with aryl iodides and triflates are reported for the first time. Under the Pd(0)/AsPh3 catalytic system (Farina's conditions), better conversions of this challenging substrate into the expected products were achieved with shorter reactions carried out under higher temperature.
