云南师范大学高端引进人才叶龙武团队在美国《有机快报》(Organic Letters)上在线刊发最新研究成果 “Construction of Spirolactams by Unexpected Oxidative Cyclization of Alkenyl Diynes via Copper Catalysis”( https://doi.org/10.1021/acs.orglett.3c00319)。文章第一作者为云南师范大学史重阳博士。
文章报道了一种新型铜基催化烯基 N-炔丙基炔酰胺的氧化环化反应。该法能在中等条件下合成具有高Z/E选择性的外环双键的螺环γ-内酰胺类化合物,且产率达81%。有趣的是,相比金催化氧化环化反映,这种铜基催化氧化环化反应显示了特有的选择性。
A copper-catalyzed oxidative cyclization of alkenyl N-propargyl ynamides is described. This protocol enables the practical synthesis of diverse spirocyclic γ-lactams bearing an exocyclic double bond with generally high Z/E selectivity in moderate to good yields. Importantly, this copper-catalyzed oxidative cyclization demonstrates a distinctive selectivity in comparison with the related gold catalysis.
