  catalyst, to obtain chiral polymers in high yields. An iodobenzenesulfonamide derivative of a cinchona alkaloid was also polymerized via self-polycondensation under the same reaction conditions. The catalytic activities of these chiral polymers were examined by using them as catalysts in the enantioselective desymmetrization of cyclic anhydrides.

  在钯催化剂存在下，对金鸡纳磺酰胺二聚体和芳族二碘化物的Mizoroki-Heck聚合进行了研究，以高收率获得了手性聚合物。金鸡纳生物碱的碘苯磺酰胺衍生物也通过相同反应条件下的自缩聚反应进行聚合。通过将它们用作环酸酐的对映选择性脱对称化反应的催化剂，可以检查这些手性聚合物的催化活性。

  chloramphenicol‐base‐derived thiourea organocatalysts, (1S,2R)‐12 a–f and (1R,2R)‐15 a–c, and their use in the enantioselective alcoholysis of meso‐anhydrides are described. In particular, hemiesters afforded excellent enantioselectivities if low loadings of (1S,2R)‐12 a–f were used. Almost no enantioselectivities were achieved with the use of (1R,2R)‐15 a–c. This technique was used to synthesize (R)‐(−)‐baclofen
