  Design and Synthesis of Thrombin Inhibitors:  Analogues of MD-805 with Reduced Stereogenicity and Improved Potency

  摘要：

  Mitsubishi's MD-805, a potent and selective inhibitor of thrombin which contains four stereogenic centers, has been the starting point for an optimization program. A systematic synthetic study resulted in thrombin inhibit;ors achiral at P2 and P3 but with a 10-fold increase in potency over the original lead. A number of 4-substituted piperidines were synthesized and examined as replacements for 2-carboxy-4-methylpiperidine at P2; 4-fluoroethylpiperidine (FEP) among others provided inhibitors (e.g. 45g) of increased potency. An enantioselective route was developed to 3(R)-methyl-1,2,3,4-tetrahydroquinolinesulfonyl chloride. Inhibitors containing this enantiomerically pure P3 (42d) had similar potency to the racemic material and provided support, with modeling studies, for the preparation of the gem 3,3-disubstituted compounds. A series of inhibitors containing the novel 3,3-dimethyl-1,2,3,4-tetrahydroquinolinesulfonyl (DMTHQS) P3 (Table 5) were synthesized and showed a similar activity profile as the monomethyl series. The combination of P3-DMTHQS, PB-FEP, and P1-arginine (45g) had a K-i of 6 nM (MD-805 K-i = 85 nM). In animal models of both venous and arterial thrombosis, one inhibitor (42e) was shown to produce a dose-dependent inhibition of thrombus formation that in some situations was superior to that of MD-805.

  for diastereoselective synthesis of the key intermediate 5 from triheterocyclic fragment and polyketide 6 for hoiamides A (1) and B (2) was developed. The main feature is the successive construction of four stereogenic centers from C33 to C36 for hoiamides A (1) through the well-established Oppolzer’s anti-aldol and Paterson’s anti-aldol methodology. Furthermore, asymmetric allylation was also utilized

  开发了一种方便的方法，用于从三杂环片段和聚酮化合物6衍生出Hoiamides A（1）和B（2）的非对映选择性合成关键中间体5。主要特征是通过完善的Oppolzer的反醛醇缩合酶和Paterson的抗醛醇缩合法，从C33到C36连续构建四个Hoiamides A（1）立体异构中心。此外，不对称的烯丙基化也被用作关键步骤，以在C32形成hoiamides A（1）的立体中心。

  The first total synthesis of chondrochloren A is accomplished using a 1,2‐metallate rearrangement addition as an alternative for the Nozaki‐Hiyama‐Kishi reaction. This transformation also avoids the inherent challenges of this polyketide segment and provides a new, unprecedented strategy to assemble polyketidal frameworks. The formation of the Z‐enamide is accomplished using a Z‐selective cross coupling

  1,2-金属盐重排加成反应作为Nozaki-Hiyama-Kishi反应的替代方法，完成了软骨素A的第一个全合成。这种转变还避免了该聚酮化合物链段的固有挑战，并提供了组装聚酮化合物骨架的新的，前所未有的策略。Z-烯酰胺的形成是通过相应酰胺与Z-乙烯基溴的Z-选择性交叉偶联来完成的。
