Wisanine, a constituent of piper guineense (a plant of which antibacterial activity has been reported and other amides of 5 - (2 - methoxy - 4, 5 - methylenedioxyphenyl) - pentadienoic acid were synthesized from 3,4 -dioxymethylen - phenel and investigated spectroscopically. The amides prepared have been tested against grampositive and gramnegative bacteria. Only some of the amides prepared show weak
