Pd-Catalyzed kinetic resolution of cyclic enol ethers. An enantioselective route to functionalised pyrans.

Functionalised cyclic enol ethers can be recovered with high levels of enantiocontrol after an asymmetric catalytic [1,3]-rearrangement reaction. These compounds can be further elaborated to a series of carbo- and heterocyclic products in good yield and with excellent levels of stereocontrol.
