Hydrogen-bond-activated palladium-catalyzed allylic alkylation via allylic alkyl ethers: challenging leaving groups

Org Lett. 2014 Mar 21;16(6):1570-3. doi: 10.1021/ol5000988. Epub 2014 Mar 12.

Abstract

C-O bond cleavage of allylic alkyl ether was realized in a Pd-catalyzed hydrogen-bond-activated allylic alkylation using only alcohol solvents. This procedure does not require any additives and proceeds with high regioselectivity. The applicability of this transformation to a variety of functionalized allylic ether substrates was also investigated. Furthermore, this methodology can be easily extended to the asymmetric synthesis of enantiopure products (99% ee).
