Palladium-catalyzed cascade reaction of haloalkynes with unactivated alkenes for assembly of functionalized oxetanes†
Abstract
A novel and efficient palladium-catalyzed aerobic cascade reaction of haloalkynes with unactivated alkenes for synthesis of functionalized oxetanes has been demonstrated. This cascade protocol, including chloropalladation and a Heck-like process, proceeds smoothly with good functional group tolerance and high selectivity.
