    acetate-tetrahydrofuran at refluxing temperature was quite effective to perform enzymatic transesterification of highly crystalline substrate, such as 2-hydroxytetracosanoic acid a representative type of long-chain α-hydroxy acid. In that case, catalytic amount of di-t-butyl p-cresol (BHT) was essential as a polymerization inhibitor for vinyl acetate.

Various analogues of agelasphin-9b (a lead compound) were synthesized, and the relationship between their structures and biological activities was examined using several assay systems. From the results, KRN7000, (2S,3S;4R)-1-O-(alpha-D-galactopyranosyl)2-(N-hexacosanoylamino)-1,3,4-octadecanetriol, was selected as a candidate for clinical application.
  • Total Synthesis of Agelagalastatin
    作者:Yong Joo Lee、Bo-Young Lee、Heung Bae Jeon、Kwan Soo Kim
    DOI:10.1021/ol061444o
    日期:2006.8.1
    The total synthesis of agelagalastatin, an antineoplastic glycosphingolipid, has been achieved. The synthesis involved an alpha-selective glycosylation of the ceramide moiety with the trisaccharide fluoride. The trisaccharide component was constructed employing the CB glycoside method which permitted a completely alpha-stereoselective galactofuranosylation.
