Highly diastereoselective Claisen rearrangements of acyclic allyl vinyl ethers bearing a chiral sulfoxide at C‐5 provide γ‐δ‐unsaturated aldehydes or ketones with up to two consecutive asymmetric centers in the molecule whilst preserving a useful vinyl sulfoxide. The reactivity of related vinyl sulfides and sulfones has also been examined in this work.
在C-5处带有手性亚砜的无环烯丙基乙烯基醚的非对映选择性克莱森重排提供了γ- δ-不饱和醛或酮,在分子中具有多达两个连续的不对称中心,同时保留了有用的乙烯基亚砜。在这项工作中还检查了相关的乙烯基硫化物和砜的反应性。
