摘要

Finally, we examined several vinylogous thioamides. The requisite 8-aroylenamines were prepared from acetophenones as described by Gupton et d.* and converted to the thiones by reaction with PzS6 in ben~ ene.~ Methylation was rapid with methyl iodide. The resulting salts were reduced in 5040% yields to the vinyl sulfides 8a-8c.
