Treatment of o-hydroxyacetophenones 2a-e with excess lithium bis(trimethylsilyl)amide followed by dialkyl carbonates gave alkyl 3-(2-hydroxyaryl)-3-oxopropanoates 3a-e. The latter substances were transformed through the reaction of their magnesium chelates with benzoyl chlorides into a series of 3-(alkoxycarbonyl)-2-arylflavones, which were subsequently elaborated into a variety of flavonoids. These

were effectively constructed from aryl aldehydes and 3-(2-(methoxymethoxy)phenyl)propiolates via a cascade Lewis acid catalyzed phenol ether deprotection/aldehyde olefination/intramolecular oxa-Michael addition reaction, and a sequential oxidation. This four-step reaction could be conducted in one-pot with high atom efficiency.
