The Claisen rearrangement of (S)-1-buten-3-yl propanoate via the (E)- and (Z)-silylketene acetal has been shown to proceed with 96–100% of 1,4-chirality transfer to afford (E,R)- and (E,S)-2-methyl-4-hexenoic acid, respectively. The variation in sense and degree with solvent and silylating agent is discussed on mechanistic grounds.
(S)-1-丁烯-3-基丙酸酯通过 (E)- 和 (Z)-甲硅烷基烯酮缩醛的 Claisen 重排已被证明进行 96-100% 的 1,4-手性转移以提供 (E ,R)- 和 (E,S)-2-methyl-4-hexenoic 酸,分别。在机理上讨论了溶剂和甲硅烷基化剂在意义和程度上的变化。
