Since many phenylvinyl ketone derivatives showed a certain anti- inflammatory activity, the indolyl group is introduced to this skeleton, and thus a series of 1, 4-penten-3-one derivatives characteristic of the structures of both phenylvinyl ketone and indole have been synthesized and characterized by elemental analyses, MS, UV-vis, and 〓 NMR as well. All these compounds are found to be trans-isomers.
