Bis-silyl-enol ethers as convenient building blocks for the design and synthesis of salicylates, pyrones, cyclohexenones, pyridones and benzophenones Bunescu, Alina , 1983- Text theses Text Hochschulschrift 2011 2011 eng electronic resourceremoteComputermedienOnline-Ressourcetext/htmlapplication/pdfOnline-Ressource graph. Darst. The present thesis describes the synthetic potential of 1,3-bis-silyl-enol ethers. They undergo regioselective cyclocondensation reactions with simple substrates providing various complex carba- and heterocycles. A new type of formal [3+3]-cyclization reaction with 2,4,6-tris(trifluoromethyl)-1,3,5-triazine is described. The mechanism was studied by the isolation of an unusual bicyclic intermediate. New and promising candidates for UV-A/B filters have been synthesized and analyzed. vorgelegt von Alina Bunescu Rostock, Univ., Mathematisch-Naturwiss.
