Uncatalyzed nucleophilic reaction of 3-formylchromones with tertiary push-pull enamines in refluxing acetonitrile gave polyfunctionalized benzophenone derivatives as a result of a [3+3] annulation in moderate to good yields.
Synthesis of 7-hydroxy-2-(2-hydroxybenzoyl)benzo[c]chromen-6-ones by sequential application of domino reactions of 1,3-bis(silyl enol ethers) with benzopyrylium triflates
Lubbe, Mathias,Appel, Bettina,Flemming, Anke,Fischer, Christine,Langer, Peter
, p. 11755 - 11759 (2007/10/03)
The domino, Michael-retro-Michael-aldol, reaction of 2,4-bis(trimethylsilyloxy)penta-1,3-diene with 3-formylchromones afforded 4-(2-hydroxybenzoyl)-2-acetylphenols, which were transformed into 6-(2-hydroxybenzoyl)chromones. The Me3SiOTf-mediate
