Whereas two equivalents of base are typically required to prepare carboxylate (CO 2-) ylides [Ph 3 P + C - (H)-alk-CO 2- ] (alk = alkanediyl) from carboxy (CO 2 H) pho

A new and efficient approach for the synthesis of oxygen and nitrogen heterocycles by organoselenium catalysis has been developed. The exo-cyclization proceeded smoothly under mild conditions with good functional group tolerance and excellent regioselectivity. Mechanistic studies revealed that 1-fluoropyridinium triflate is key for oxidative cyclization.
