diastereoselectively introduce α-substituents to chiral β-hydroxy esters, however, the yields of reactions in which longer chain alkyl halides are used can be disappointing. To provide a more robust protocol for the alkylation of β-hydroxy esters, we prepared a variety of long-chain allylic iodides with the view that the greater reactivity of the allylic system would
Frater-Seebach 烷基化是一种将 α-取代基非对映选择性地引入手性 β-羟基酯的高效方法,然而,使用较长链烷基卤化物的反应产率可能令人失望。为了为 β-羟基酯的烷基化提供更可靠的方案,我们制备了多种长链烯丙基碘,认为烯丙基系统的更大反应性将
