Eight-membered nitrogen-containing heterocycles were straightforwardly produced by a nickel-catalyzed cycloetherification and subsequent Claisen rearrangement of secondary and tertiary alcohols. In particular, a one-pot transformation was achieved with tertiary alcohols in moderate to good yields. This operationally simple reaction is tolerant of many functional groups and applicable to the synthesis
通过镍催化的环醚化和随后的仲醇和叔醇的克莱森重排直接产生八元含氮杂环。特别是,用叔醇以中等至良好的产率实现了一锅法转化。这种操作简单的反应可耐受多种官能团,适用于合成各种中环含氮杂环。
