structures of four natural classes of prenylated aromatic compounds with 2,3-epoxy, 2,3-dihydroxy, and cyclization with an ortho-phenolic hydroxyl to give a pyran or furan ring moiety are frequent and inevitable. Based on rigorous literature research and a series of chemical transformation experiments, a rule for the rapid determination of these four classes of prenylated derivates based on 13C NMR data was
在阐明具有 2,3-环氧、2,3-二羟基的四类天然异戊二烯化芳族化合物的结构以及与邻苯酚羟基环化以产生吡喃或呋喃环部分的结构时,经常会出现错误并且不可避免。在严谨的文献研究和一系列化学转化实验的基础上,制定了基于13 C NMR 数据快速测定这四类异戊二烯化衍生物的规则,并据此报告了这些片段的 57 次修正。
