TL;DR: In this article, the starting materials were prepared by the reaction of 4-hydroxycoumarin with trifluoroacetic anhydride and methyl 2-chloro-2-oxoacetate in the presence of trimethylsilylchloride.
Journal ArticleDOI
Synthesis of trifluoromethyl-substituted arenes, cyclohexenones and pyran-4-ones by cyclocondensation of 1,3-bis(silyloxy)-1,3-butadienes with 4,4-dimethoxy-1,1,1-trifluorobut-3-en-2-one: influence of the lewis acid on the product distribution.
TL;DR: The TiCl(4)-mediated formal [3 + 3] cyclocondensation of 1,3-bis(trimethylsilyloxy)-1, 3-butadienes with 4,4-dimethoxy-1,1, 1-trifluorobut-3-en-2-one afforded a variety of functionalized 4-meth oxygen-6-(triffluoromethyl)salicylates and 3-m
Journal ArticleDOI
3-Methoxalylchromones – versatile reagents for the regioselective synthesis of functionalized 2,4′-dihydroxybenzophenones, potential UV-filters
Viktor O. Iaroshenko,Viktor O. Iaroshenko,Alina Bunescu,Anke Spannenberg,Linda Supe,Maria Milyutina,Peter Langer +6 more
TL;DR: The reaction of 1,3-bis-silyl enol ethers with 3-methoxalylchromones affords a great variety of functionalised 2,4'-dihydroxybenzophenones, which are promising candidates for the synthesis of the novel UV-A/B and UV-B filters.
Journal ArticleDOI
Reaction of 1,3-Bis(trimethylsilyloxy)-1,3-butadienes with 2,4,6- Tris(trifluoromethyl)-1,3,5-triazine: Planning and Serendipity
TL;DR: The synthesis of annulated 2,6-bis(trifluoromethyl)pyrimidines and the corresponding nucleosides of purine isosteres by the IEDDA reaction of 2,4, 6-tris(trimethylsilyloxy)-1,3,5-triazine with electron-excessive heteroaromatic amines, anilines, and enamines is reported.
Journal ArticleDOI
Formal [3+3] cyclocondensations of 1,3-bis(silyloxy)-1,3-butadienes with 1-chloro-1,1-difluoro-4,4-dimethoxybut-3-en-2-one and 1,1-difluoro-4,4-dimethoxybut-3-en-2-one. Regioselective synthesis of fluorinated salicylates and pyran-4-ones

TL;DR: In this article, the Me3SiOTf-mediated cyclocondensation of the same building blocks provided CF2Cl- and CF2H-substituted pyran-4-ones, while the cyclization of C4-addienes with 1,1-difluoro-4,4-dimethoxybut-3-en-2-one failed.
