palladium-catalyzed dearomatization of electron-poor arenes, we report herein that various 2-nitrobenzofurans efficiently undergo a dearomative (3+2) cycloaddition with vinylcyclopropanes. This new method gives access to a wide variety of cyclopenta[b]benzofuran derivatives in a straightforward manner.
在钯催化的缺电子芳烃脱芳构化的背景下,我们在本文中报告了各种 2-硝基苯并呋喃与乙烯基环丙烷有效地进行脱芳基 (3+2) 环加成。这种新方法可以直接获得多种环戊二烯[b]苯并呋喃衍生物。
