  Enantiodifferentiation in Taste Perception of the phyllodulcins

  摘要：

  Both enantiomers of phyllodulcin 1 have been prepared. Ester 2 was synthesized in a Wittig reaction from O-benzyl isovanillin. The corresponding stilbene carboxylic acid 3 could be cyclized with CF3CO2H to produce the 3'-benzyl ether 4 of (+/-)-phyllodulcin. Acylation with (1R,4S)-camphanoyl chloride gave first 5 and after hydrogenolysis of the benzyl ether group in 5 the diastereomeric esters 6. The diastereomerically pure 8-(1R,4S)-camphanoate (+)-6 of (R)-phyllodulcin could be isolated by repeated recrystallization. With (1S,4R)-camphanoyl chloride the enantiomeric 8-(1S,4R)-camphanoate (-)-6 of O-phyllodulcin could be prepared via ent-5 from a mixture of the diastereomeric esters ent-6. Ethanolysis of (+)-6 gave (R)-phyllodulcin [(+)-1] with 99% ee. The enantiomeric (S)-(-)-1 with 98% ee could be obtained from (-)-6. While (+)-1, the enantiomer occuring in fermented leaves of amacha, has an intense sweet taste, the enantiomer (-)-1 is completely tasteless.
