    摘要:
    描述了由内消旋戊二酸酐合成γ-氨基酸和γ-内酰胺衍生物的第一种方法。TMSN 3的有机催化去对称性依赖于受控生成的聚苯乙烯键合碱介导的亲核叠氮化铵物种,以促进有效的甲硅烷基叠氮化。将酰基叠氮化物中间体进行Curtius重排以得到相应的异氰酸酯后,水解/醇解可提供均匀高收率的γ-氨基酸及其N受保护的同行。结果表明,相同的中间体原位经历了前所未有的脱羧-环化级联反应,无需使用任何其他活化剂即可提供合成有用的γ-内酰胺衍生物。机械学的见解在后一个过程中调用了非常规的γ- N-羧基酸酐(γ-NCA)的中介作用。在使用这种转化方法制备的实例中,有8种具有重大医学意义的API /分子。

  • Highly Enantioselective Thiolysis of Prochiral Cyclic Anhydrides Catalyzed by Amino Alcohol Bifunctional Organocatalysts and Its Application to the Synthesis of Pregabalin
    作者:Hong-Jun Yang、Fang-Jun Xiong、Xiao-Fei Chen、Fen-Er Chen
    DOI:10.1002/ejoc.201300464
    日期:2013.7
    Asymmetric thiolysis of prochiral cyclic anhydrides was achieved with our developed chiral sulfonamide and squaramide bifunctional organocatalysts based on amino alcohol scaffolds. The corresponding thioesters were obtained in high yields with excellent enantioselectivities. The usefulness of this methodology was demonstrated in the enantioselective synthesis of pregabalin.

  • Development of Bifunctional Thiourea Organocatalysts Derived from a Chloramphenicol Base Scaffold and their Use in the Enantioselective Alcoholysis of<i>meso</i>Cyclic Anhydrides
    作者:Lin-Jie Yan、Hai-Feng Wang、Wen-Xue Chen、Yuan Tao、Kai-Jun Jin、Fen-Er Chen

    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
    新的氯霉素基硫脲有机催化剂(1 S,2 R)-12 a - f和(1 R,2 R)15 a - c的合成及其在介孔酸酐的对映选择性醇解中的应用描述。特别是,如果使用低负荷的(1 S,2 R)-12 a – f负载,半酯具有出色的对映选择性。使用(1 R,2 R)‐ 15 a – c几乎没有达到对映选择性。该技术用于合成(R)-(-)-baclofen。
