The 1,3-rearrangement of allylic derivatives has rarely been reported, except for allylic alcohols. Herein, we describe an iridium-catalyzed 1,3-rearrangement of readily available allylic ethers to access the difficultly prepared allylic ethers with a large steric hindrance. The developed method shows a broad substrate scope and could be used in the late-stage modification of several natural products

The minimising of torsional strain and non-bonding interactions is proposed as the explanation of high diastereoselectivity observed in the epoxidation of cycloalkenyl alcohols. reported for twenty three examples. The resulting 2,3-epoxyalcohols are key intermediates in the synthesis of tricyclic 1, 2-diols and beta-hydroxy ketones
