The study of the π-facial diastereoselectivity in the [4+3] cycloaddition reaction of thirteen different chiral 2-substituted furans with oxyallyl cations, under sonochemical and/or thermal conditions, is presented. In almost all studied furans, a cis diastereoselectivity and a high endo diastereoselectivity is observed. Decreasing the distance between the closest stereocenter of the chiral auxiliary and the reactive C2-carbon of the furan ring, increases the π-facial diastereoselectivity, especially by using chiral furyl-sulfoxides.
The configurational assignment of the optically active 5-(1-hydro- peroxyethyl)-3-ethoxycarbonyl-2-methylfuran and its alcohol by exciton- coupled circular dichroism (ECCD)

The absolute configuration of the furan-derived hydroperoxide 1 and its alcohol 2, readily available in optically active form by kinetic resolution of the racemic hydroperoxide with horseradish peroxidase (HRP), was determined by the exciton-coupled circular dichroism (ECCD) method on their 2-naphthoate derivatives 4.
