Tri and you will succeed! A new type of formal [3+3] cyclization reaction of 2,4,6‐tris(trifluoromethyl)‐1,3,5‐triazine with 1,3‐bis(trimethylsilyloxy)‐1,3‐butadienes has been discovered that provides a convenient approach to functionalized 2,6‐bis(trifluoromethyl)‐1,4‐dihydro‐4‐oxopyridones (see scheme). The mechanism was studied by the isolation of an unusual tricyclic intermediate.
Tri,您将成功!发现了一种新型的2,4,6-三(三氟甲基)-1,3,5-三嗪与1,3-双(三甲基甲硅烷氧基)-1,3-丁二烯的正式[3 + 3]环化反应,提供了一种方便的方法来官能化2,6-双(三氟甲基)-1,4-二氢-4-氧代吡啶酮(参见方案)。通过隔离不寻常的三环中间体研究了该机理。
