The Ru-catalyzed intramolecular [5+2] cycloaddition of cyclopropylenynes is investigated with respect to the regio- and diastereoselectivity as well as the functional group compatibility of the reaction. Evidence for the mechanism as occurring through a ruthenacyclopentene intermediate is elucidated from 1) the study of the diastereoselectivity of the cycloaddition; 2) the effect of variation of substituents

In this paper, diastereoselective epoxidation of substituted cyclohexenes (substrates 1-7) by dioxiranes generated in situ from ketones and Oxone was systematically investigated. The results revealed that the diastereoselectivity was determined by the steric and field effects of both dioxiranes and substrates, and high diastereoselectivity can be achieved by tuning the ketone structure. Among the ketones

Echinopines A and B [(+)-1 and (+)-2], two naturally occurring compounds characterized with a unique [3.5.5.7] carbon framework, have been synthesized in both enantiomeric and racemic forms. Their total synthesis involves a novel intramolecular rhodium-catalyzed cyclopropanation (4 --> 16) and a samarium diiodide-mediated ring closure (3 --> 37).
Echinopines A 和 B [(+)-1 和 (+)-2] 是两种天然存在的化合物,具有独特的 [3.5.5.7] 碳骨架,已以对映体和外消旋形式合成。他们的全合成涉及新型分子内铑催化的环丙烷化反应 (4 --> 16) 和二碘化钐介导的闭环 (3 --> 37)。
