Golden circle: Two gold‐catalyzed oxidative cyclizations of 1,5‐enynes using 8‐methylquinoline N‐oxide are presented (see example). Experimental results indicate that both reactions proceed through prior oxidation of alkyne to form α‐carbonyl intermediates and subsequent intramolecular carbocyclization.
金色圆圈:介绍了使用8-甲基喹啉N-氧化物的两个金催化的1,5-烯炔的氧化环化反应(请参见示例)。实验结果表明,这两个反应都是通过炔烃预先氧化形成α-羰基中间体以及随后的分子内碳环化而进行的。
