dynamic electrocyclization process, showing an innovative, unconventional reaction sequence. This method enables precise control of regioselectivity in competitive 6π and 8π electrocyclization reactions, rendering the final products rich in functional groups that can be further developed for the synthesis of nitrogen-containing scaffolds. This is an unprecedented example of the selective synthesis of seven-
我们提出了一种通过动态电环化过程将恶唑骨架重排为氮杂卓和吡咯的新方法,展示了一种创新的、非常规的反应序列。该方法能够精确控制竞争性6π和8π电环化反应的区域选择性,使最终产物富含官能团,可进一步开发用于合成含氮支架。这是通过动态电环化开环或闭环选择性合成七元和五元杂环的前所未有的例子。
