  • ASYMMETRIC MICHAEL ADDITION OF THIOPHENOL TO MALEIC ACID ESTERS
    作者:Hiroyuki Yamashita、Teruaki Mukaiyama
    DOI:10.1246/cl.1985.363
    日期:1985.3.5
    (S)-()-Diisopropyl phenylthiosuccinate (81% optical purity) is prepared in 95% yield by the asymmetric Michael addition of thiophenol to diisopropyl maleate in the presence of a catalytic amount of cinchonine. The succinate thus prepared is transformed into (R)-(+)-3,4-epoxy-1-butanol without racemization.

    Hydrophobic α(1→4)glucopyranose polymers with enhanced degradation properties are described. Between the α(1→4)glucopyranose polymeric portion and the hydrophobic portion exists a linker portion having a chemistry that facilitates degradation of the polymer. Diester and carbonate ester linker chemistries are exemplified. Biodegradable matrices can be formed from these polymers, and the matrices can be used for the preparation of implantable and injectable medical devices wherein the matrix is capable of degrading in vivo at an increased rate. Matrices including and capable of releasing a bioactive agent in vivo are also described.
