Reactivities of a new diene N,N-dimethylamino-3-methylthiobutadiene (7), prepared in situ by treatment of the methiodide of thioenaminone 5 with triethylamine, with several dienophiles as a Diels-Alder diene, were investigated. In general, the cycloaddition reactions were completed at low temperature for short periods, which showed that the diene has a high reactivity as a Diels-Alder diene.
