✦ Synopsis

Stereochemistry of the Diels-Alder reaction of ethyl Z-and E-2-ptolylsulfinylmethylenepropionate with cyclopentadiene has been studied. The high diastereoselectivity was observed especially in the case of exo-cycloaddition.

We have previously reported that (+)-(R)S p-tolyl vinyl sulfoxide 1 is a
