| Abstract: | 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 1H- and 13C-NMR. spectra of the compound (II) are discussed. |
