A straightforward two-step entry to α-oxgenated β,γ-unsaturated ketones from readily available α,β-unsaturated ketones is disclosed. It was found that bis(allylic) alcohols undergo a skeletal rearrangement in the presence of 1 mol% of cheap and non-corrosive p-toluenesulfonic acid. Computational studies were conducted to support the mechanism and to rationalise the influence of the catalyst acidity on the product selectivity.

催化重排策略合成α-氧化的β，γ-不饱和酮†

公开了从容易获得的α，β-不饱和酮直接进入α-加氧的β，γ-不饱和酮的两步法。发现双（烯丙基）醇在1mol％的廉价且无腐蚀性的对甲苯磺酸的存在下发生骨架重排。进行了计算研究以支持该机理并合理化催化剂酸度对产物选择性的影响。
