Oxy-Cope rearrangement of diastereomeric l,5-hexadien-3-ols, new key intermediates for terpenoids pio-duction in industrial scale, were investigated in neat systems and solvent assisted systems. Various solvents affecting the selectivity of [3,3]-shift were classified by means of NMR studies on hydroxyl proton exchange time.
在纯系统和溶剂辅助系统中研究了非对映异构体 l,5-己二烯-3-醇的 Oxy-Cope 重排,这是工业规模生产萜类化合物的新关键中间体。通过对羟基质子交换时间的 NMR 研究,对影响 [3,3] 位移选择性的各种溶剂进行了分类。
