Cyclisation of chiral non-racemic phenylsulphonylvinyl epoxy ethers, produced using the Sharpless epoxidation reaction, has been used to prepare a series of enantiomerically enriched 2-aryl-4-(α-hydroxybenzyl)-4,5-dihydrofuran derivatives.Reduction of these compounds using triethylsilane and BF3-diethyl ether gave the corresponding tetrahydrofuran derivatives stereoselectively.Attempts to convert either the dihydro- or tetrahydro-furan derivatives into lignans belonging to the 2,6-diaryl-3,7-dioxabicyclooctane series so far proved unsuccessful.
