A vanadium-catalyzed method for the oxidation of prochiral aryl, allylic selenides with tandem sigmatropic rearrangement has been developed. This protocol has been screened on a series of substrates to test for its generality and effectiveness. The applicability of this methodology to the synthesis of enantiomerically enriched allylic alcohols has been studied on a series of chiral oxazole-containing systems with a diastereomeric ratio (d.r.) of up to 85 : 15. The chiral transfer observed in the allyl alcohol products is the result of a net 1,9- and/or 1,10-induction. Finally, the first example of a selenium-oxygen nonbonding interaction in oxazole-containing selenide appears to have been observed via X-ray crystal analysis.

The efficient synthesis of a series of 2°allylic alcohols from a vanadium-catalyzed oxidation of suitably disposed allylic selenides with tandem [2,3] sigmatropic rearrangement is outlined.
