The palladium‐catalyzed tandem reactions of 2,7‐alkadiynylic carbonates with 2,3‐allenyl sulfamides for the syntheses of fused tricycles such as 1,3,6,7,8,9‐hexahydrofuro[3,4‐h]isoquinoline, 2,3,6,7,8,9‐hexahydro‐1H‐pyrrolo[3,4‐h]isoquinoline, and 2,3,4,7,8,9‐hexahydro‐1H‐cyclopenta[h]isoquinoline derivatives have been developed. A mechanism has been proposed based on the isolation of a by‐product
2,7-烷二炔碳酸酯与2,3-烯丙基磺酰胺的钯催化串联反应,用于合成稠合三环,如1,3,6,7,8,9-六氢呋喃[3,4- h ]异喹啉, 2,3,6,7,8,9-六氢-1 H-吡咯并[3,4- h ]异喹啉和2,3,4,7,8,9-六氢-1H-环戊[ h ]异喹啉已经开发了衍生物。已经提出了一种基于副产物分离的机制。
