N‐Isobutyl‐11‐(3, 4‐methylenedioxyphenyl)‐undeca‐2,4,6‐ trans, trans, trans ‐trienoic amide (II) and N‐isobutyl‐11‐(3,4‐methylenedioxyphenyl)‐undeca‐2,8,10‐ trans, trans, trans ‐trienoic amide (III), two of the three possible structures of the alkaloid piperstachine, have been synthesized. Compound (III) has been found to be identical with piperstachine. The 1 H‐ and 13 C‐NMR. spectra of the compound (II) are discussed.
