The reaction of 1,3-bis-silyl enol ethers with 3-acyl-and 3-formylbenzopyrylium triflates, which can be generated in situ from 3-acyl-and 3-formylchromones, affords a great variety of functionalised 2,4Ј-dihydroxybenzophenones and 4-(2-hydroxybenzoyl)salicylates. These products are formed by a domino Michael/retro-Michael/Mukaiyama-aldol reac-

quence. -A versatile and regiospecific microwave-assisted one-pot three-component synthesis of 2,4-di-and 2,4,7-trisubstituted quinolines by a consecutive, microwave-assisted one-pot three-component coupling-cyclocondensation-sulfur extrusion sequence is described. The quinolines display intense blue fluorescence and their spectral properties can be rationalized by rapid DFT-ZINDO-CI calculations. -(ROTZOLL, S.; WILLY, B.; SCHOENHABER, J.; ROMINGER, F.; MUELLER*, T.
