The Diels-Alder cycloaddition between several 2-, and 3-substituted furans and E-i,2bis(phenylsulfonyl)ethylene have been carried out in high yields. Stereoselectivity observed in the case of 2-sustimted furans has been explained by means of the MM3-transition state model. The model had to be refine
