Enantioselective Palladium-Catalyzed [3 + 2] Cycloadditions of Trimethylenemethane with Nitroalkenes
Publikováno v:
Organic Letters. 14:234-237
Nitroalkenes readily undergo palladium-catalyzed [3 + 2] cycloaddition with trimethylenemethane to generate nitrocyclopentanes in excellent yield and enantioselectivity. Furthermore, the products thus formed are highly versatile synthetic intermediat
