New rhodium(II)‐catalyzed or thermally induced intramolecular alkoxy group migration of N‐sulfonyl‐1,2,3‐triazoles has been developed, affording divergent synthesis of 1,2‐dihydroisoquinoline and 1‐indanone derivatives according to different conditions. N‐Sulfonyl keteneimine is the key intermediate for the synthesis of dihydroisoquinoline, whereas the aza‐vinyl carbene intermediate results in the
已开发出新的铑(II)催化或热诱导的N-磺酰基-1,2,3-三唑的分子内烷氧基迁移,可根据不同条件提供1,2-二氢异喹啉和1-茚满酮衍生物的多样化合成。N-磺酰基酮亚胺是合成二氢异喹啉的关键中间体,而氮杂-乙烯基卡宾中间体则导致1-茚满酮的形成。
