2,3-Dimethylene-2,3-dihydrothiophene (the analogue of o-xylylene) is generated in situ from 3-(trimethylanunoniuinmethyl)-2-(trimethylsilylmethyl) thiophene iodide (7) by a fluoride induced 1,4-elimination process, and is identified by several [4+2] cycloadducts obtained in high yields.

The present study describes the synthesis and in vitro pharmacology of a novel series of dopaminergic agents in which the classical phenylethylamine pharmacophore is replaced by a thienylethylamine moiety. In general, the novel compounds showed a moderate affinity for the dopamine (DA) D-2 and D-3 receptors. When the thienylethylamine moiety is fixed in a rigid system, the affinity for the DA receptor is significantly increased. However, in the tricyclic hexahydrothianaphthoxazine structure, the affinity for the DA receptors is diminished.
