Reaction of 1,3-Bis(trimethylsilyloxy)-1,3-butadienes with 2,4,6-Tris(trifluoro-methyl)-1,3,5-triazine: Planning and Serendipity. — A new type of formal [3 + 3] cyclization reaction of triazine (I) with silyloxybutadienes (II) is discovered. The reac-tion provides a convenient approach to functionalized oxopyridones, compounds which are not readily available by other methods. The mechanism is studied by isolation of an unusual tricyclic intermediate. — (IAROSHENKO*, V. O.; BUNESCU, A.; SPANNENBERG, A.; LANGER, P.; Chem. Eur.
