Reactions of o-quinone methides with pyridinium methylides: a diastereoselective synthesis of 1,2-dihydronaphtho[2,1-b]furans and 2,3-dihydrobenzofurans.
TL;DR: A simple, general route to the 1,2-dihydronaphtho[2,1-b]furans and 2,3- dihydrobenzofurans substituted at C-2 by an acyl or aryl group, starting from phenolic Mannich bases and pyridinium ylides has been developed.
