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.

Cobalt-catalyzed aerobic oxidative cyclization of β,γ-unsaturated oximes
Cobalt complex Co(nmp)2 can efficiently catalyze the aerobic oxidative 5-exo cyclization of β,γ-unsaturatedoximes to afford isoxazolines. The key cyclization step involves the generation of carbon-centred radicals. The products are largely dependent on the reaction conditions. The oxidative termination products 2 were produced predominantly when the reaction was carried out in i-PrOH, whereas the
