Abstract
A regio- and stereoselective cycloaddition of 6-chloromethyl-6-hydroxycyclohexa-2,4-dienones with benzofuran leading to dihydrobenzofuran annulated bicyclo[2.2.2]octenones having a β,γ-enone chromophore has been reported. Further transformation of adducts into benzannulated oxa-polyquinanes and dihydrobenzofuran annulated bicyclo[4.2.0]octenones has also been described.
