    摘要:
    In this paper we report on a efficient and flexible synthetic route towards the total syntheses of the dihydrocoumarine derivatives hydrangenol (1), phyllodulcin (1a) and macrophyllol (6b). The syntheses started with a readily available phosphonium salt 2 and suitable modified benzaldehydes 3/3a/3b resulting in 46 to 61% overall yields in three to four-steps sequences. The racemic products could be separated by chiral HPLC. The evidence of the(R)-enantiomer for sweetness could be demonstrated for la. (C) 2003 Elsevier Ltd. All rights reserved.

    日期:1991.9
    First total synthesis of AI-77-B (1), a gastroprotective substance from Bacillus pumilus AI-77, was achieved in a stereoselective and convergent manner. In this synthesis, the dihydroisocoumarin part 2 was constructed in one step through 1,2-addition of the benzylic anion 17b to Boc-L-leucinal 7b. The hydroxy amino acid 4 was elaborated from (R)-glutamic acid in a highly stereoselective manner. Condensation

  • Enantiodifferentiation in Taste Perception of the phyllodulcins
    作者:Reinhard Zehnter、Hans Gerlach
    DOI:10.1016/0957-4166(95)00367-x
    日期:1995.11
    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.
