A Ni(II)-catalyzed tandem cyclopropane ring opening and radical alkylation of the aromatic ring using unactivated alkyl bromide-tethered alkylidenecyclopropanes (ACPs) have been described in this paper. This ring-forming process exhibits a broad substrate scope with a variety of primary alkyl bromides and aromatic rings, affording diversified benzo[b]naphtho[1,2-d]azepine derivatives in moderate-to-excellent
本文描述了Ni(II)催化的串联环丙烷丙烷开环和使用未活化的烷基溴-束缚的亚烷基环丙烷(ACP)对芳环进行自由基烷基化。这种成环过程显示出具有多种伯烷基溴和芳族环的广泛底物范围,在温和条件下以中等至优异的产率提供了多种苯并[ b ]萘[1,2- d ] a庚因衍生物。在包括氘标记检查在内的几个对照实验的基础上,提出了合理的反应机理。还对获得的多环产物进行了进一步的衍生化。

A facile synthetic method for preparation of bicyclo[4.2.0] nitrogen heterocycles has been developed via a thermal induced intramolecular [2 + 2] cycloaddition reaction of allene-ACPs. The DFT calculations indicate that this intramolecular cycloaddition proceeds in a concerted manner and a strained small ring is essential.
