Rapid construction: We report the first successful implementation of a catalytic tandem carbocyclization/annulation cascade reaction (e.g., see scheme) using acetal–allene or ketal–allene substrates through a dealkoxylative mode. This gold catalysis enables a rapid stereocontrolled construction of oxacyclic or carbocyclic frameworks.
快速构建:我们报道了使用乙醛-丙二烯或缩酮-丙二烯底物通过脱氧羰基化模式成功实现催化串联碳环化/环化级联反应(例如,参见方案)的第一个成功实施方法。这种金催化作用使得能够快速立体控制氧杂环或碳环骨架的构建。
