On the other side of the Traxler? The stereochemical outcome of the allylation reaction of 3,3‐disubstituted allylzinc species with aldehydes shows that the aryl or alkyl group of the electrophilic carbonyl reactant occupies a pseudoaxial position in the Zimmerman–Traxler transition state to avoid gauche interactions (see scheme).
在 Traxler 的另一边?3,3-二取代烯丙基
锌与醛的烯丙基化反应的立体
化学结果表明,亲电羰基反应物的芳基或烷基在Zimmerman-Traxler过渡态中占据假轴位置,以避免gauche相互作用(参见方案)。
