β¦ Synopsis
Diastereofacial selectivities observed for Diels-Alder cycloadditions of achiral dienes with chiral vinyl sulfoxides are rationalized in terms of electrostatics.
The "nucleophilic" diene adds to the electron-poor face of the "electrophilic" dienophile.

Excellent diasterofacial selection has been observed in asymmetric Diels-Alder cycloadditions of E,E-triene-imides 3 and 6.
