W(CO)5(L)-catalyzed cyclization of α-alkynyl-β-dicarbonyl derivatives : synthesis of methylenelactones, furans, and methylenecyclopentanes
W(CO)5(L)-Catalyzed cyclization of α-alkynyl-β-keto acids, keto esters, and diketones provides methylenelactones, furans, and methylenecyclopentanes via 5-exo-dig cyclization. Also, the present approach can be further applied to 5-endo-dig cyclization.
