n-rearrangement (n = 3, 5, 7, 9) of allylic alcohols. In some cases, the rearrangement reactions joined isolated C–C double or triple bonds to generate conjugated polyene or enyne structure motifs. We used the 1,3-rearrangement reaction of an allylic alcohol in hot water as part of an attractive new strategy for construction of the polyene natural product navenone B by iterative use of a Grignard reaction
首次报道,作为弱酸性催化剂的热水有效地促进了烯丙醇的1,n重排(n = 3、5、7、9 )。在某些情况下,重排反应会连接孤立的C双键或C键,从而生成共轭多烯或烯结构的基序。我们使用了烯丙醇在热水中的1,3-重排反应作为通过反复使用格利雅(Grignard)反应构建多烯天然产物navenone B的有吸引力的新策略的一部分,将所得烯丙基的1,3-重排酒精和随后氧化的重排产物。
