Guineensine ((2E,4E,12E)-13-(benzo[d][1,3]dioxol-5-yl)-N-isobutyltrideca-2,4,12-trienamide) is a plant-derived natural product that inhibits reuptake of the endocannabinoid anandamide with sub-micromolar potency. We have established a highly efficient tot

A total synthesis of guineensine, a secondary metabolite of the Piperaceae family, has been executed in 12 steps with an overall yield of 27%. Key steps in the synthesis featured novel application of a Julia-Kocienski olefination reaction which effectively constructed alkenamide skeleton. This contributes a unique approach to the synthesis of the piperamide alkaloids.

The structures of piperolein acids guineensine and wisanine have been confirmed by synthesis.UV irradiation of trans piperolein B acid ester gave the cis-isomer reported in the literature as the trans-isomer.The trans-2, trans-4 ethylenic bonds in guineensine and wisanine were introduced by reacting piperolein B aldehyde and 2-methoxy piperonal with the appropriate Wittig or Reformatsky reagent.

Wittig reaction of 8-(tetrahydro-2'-pyranyloxy)octanal (IV) with (3',4'-methylenedioxyphenyl)triphenylphosphonium bromide yields 9-(3',4'-methylenedioxyphenyl)-1-(tetrahydro-2''-pyranyloxy)non-8-trans-ene (V).V on treatment with PTS in methanol followed by subsequent oxidation with pyridinium chlorochromate affords 9-(3',4'-methyleneedioxyphenyl)non-8-trans-en-1-al (VII).VII on modified Wittig reaction with ethyl α-diethylphosphonocrotonate gives the conjugate ester (VIII) which on alkaline hydrolysis provides 13-(3',4'-methylendioxyphenyl)trideca-2,4,12-trans,trans,trans-trienoic acid (IX).IX on condensation with N-isobutylamine using POCl3 in the presence of triethylamine furnishes I.
