A Cu-catalyzed oxidative ipso-annulation of activated alkynes with unactivated alkanes for the synthesis of 3-alkyl spiro[4,5]trienones is described. This method allows the formation of two carbon-carbon bonds and one carbon-oxygen bond in a single reaction through a sequence of C-H oxidative coupling, ipso-carbocyclization and dearomatization.
描述了一种铜催化的未活化烷烃与活化炔烃的氧化本位环化反应,用于合成3-烷基螺[4,5]三烯酮。该方法通过C-H氧化偶联、本位碳环化和去芳构化序列,在单一反应中形成两个碳-碳键和一个碳-氧键。
