Easy to N‐cycle: The efficient synthesis of azepine derivatives was achieved by Rh‐catalyzed tandem 2,3‐rearrangement involving the heterocyclization of N‐allenylnitrone intermediates (see scheme; cod=1,5‐cyclooctadiene, tppms=sodium diphenylphosphinobenzene‐3‐sulfonate).
易于N循环:通过Rh催化的串联2,3重排涉及N-亚烯基硝烯中间体的杂环化,实现了氮杂衍生物的有效合成(参见方案; cod = 1,5-环辛二烯,tppms =二苯基膦基苯钠-3 -磺酸盐)。
