Synthesis of polyketide-type phenols by domino 'Michael/retro-Michael/Aldol' reactions of 3-formylchromones with silyl enol ethers derived from ethyl 3,5-dioxohexanoate

experimental part, p. 4099 - 4105 (2009/09/30)

Highly functionalized polyketide-type phenols were prepared by domino 'Michael/retro-Michael/aldol' reactions of 3-formylchromones with 1-ethoxy-1,3,5-tris(trimethylsilyloxy)-1,3,5-hexatriene and its synthetic precursor, ethyl 3,5-bis(trimethylsilyloxy)-2
