Abstract: 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 (Farinas conditions), better conversions of this challenging substrate into the expected products were achieved with shorter reactions carried out under higher temperature.
