Synthesis of substituted 3-furanoates from MBH-acetates of acetylenic aldehydes via tandem isomerization–deacetylation–cycloisomerization: access to Elliott's alcohol
A new method for the synthesis of 5-substituted furan-3-carboxylates from MoritaâBaylisâHillman acetates of acetylenic aldehydes is reported. The process involves palladium-catalyzed isomerization followed by base-promoted deacetylation and cycloisomerization reactions. The utility of this chemistry is further demonstrated by the synthesis of Elliott's alcohol, a key intermediate of the pyrethroid resmethrins.
