The stereochemistry of cycladducts obtained through the reaction of mesoionic thiazolones with ethylenic dipolarophiles is established. The dipole-dipolarophile approach is discussed in terms of interactions between the frontier orbitals. When the dipolarophile is acrylonitrile we note the importance of the destabilising interaction the HOMO orbitals. When the dipolarophile is vinyl ethyl ether we
