chloride–diamine sulfide coupling reactions followed by the tandem Claisen rearrangement of macrocycles 2a and 2b as precursors, respectively. The reactivity of the titled macrocycles with sometransition and heavy metal ions was examined. The most salient feature of the reactions is the mercurated dihydrobenzofuran 4 derived from 3b and Hg(OAc)2. The X-ray crystalstructures of 4 as well as 2a and
通过二酰氯-二胺硫化物的偶联反应,然后将大环化合物2a和2b串联串联进行克莱森重排,分别合成了两个新颖的含硫酰胺基乌鸦烷3a(N 2 S)和3b(N 2 S 2)。检查了标题大环与一些过渡离子和重金属离子的反应性。反应的最显着特征是衍生自3b和Hg(OAc)2的汞化二氢苯并呋喃4。4以及2a和2b的X射线晶体结构 被揭示。
