The most common cinnamoyl anilines are avenanthramides, which are natural antioxidants found in oats. This is a rather uncommon and not well-investigated group of antioxidants. This paper deals with 2-arylidenemalonic acid dianilides – cinnamoyl anilines which are decorated with an additional arylaminocarbonyl moiety at α-position of double bond. The DPPH scavenging activity of the title compounds is slightly lower in comparison to the corresponding cinnamoyl anilines. On the other hand, the title dianilides are more active than cinnamic acid anilides containing an additional carboxylic group in the α-position of double bond.
