Palladium-Catalyzed Oxime Assisted Intramolecular Dioxygenation of Alkenes with 1 atm of Air as the Sole Oxidant
摘要:
This paper describes a palladium-catalyzed oxime assisted intramolecular dioxygenation of alkenes by using 1 atm of air as the sole oxidant under extremely mild conditions, which demonstrated the feasibility of incorporating atmospheric oxygen into synthetically useful products under 1 atm of air at room temperature.

The first catalytic enantioselective 1,4-iodofunctionalizations of conjugated dienes have been developed. Starting from beta,gamma,delta,epsilon-unsaturated oximes and 4-Ns hydrazones, these N-iodosuccinimide-mediated reactions are catalyzed by newly modified tertiary aminothiourea derivatives and furnish Delta(2)-isoxazoline and Delta(2)-pyrazoline derivatives, respectively, containing an (E)-allyl iodide group at the quaternary stereogenic center generally in high yield and with excellent enantioselectivity (up to 98.5:1.5 er).
