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.
