Intramolecular nitrile oxide cycloaddition reactions on (Z)- and (E)-chiral allyl ethers occur with poor to good stereoselectivity (diastereoisomeric ratios up to 86: 14), which depends on the double bond configuration as well as on steric and stereoelectronic effects.
(Z)-和(E)-手性烯丙基醚的分子内一氧化氮环加成反应发生时,立体选择性差至良好(非对映异构体比例高达86:14),这取决于双键构型以及空间和立体电子效应。
