  通过钯催化的氨基酸衍生物脱羧偶联合成高烯丙基胺

  摘要：

  受保护的高烯丙基胺是通过α-氨基酸衍生物的脱羧偶联合成的。催化 CC 键形成反应依赖于生物启发的 α-氨基酸脱羧金属化，以产生 α-氨基阴离子等价物。α-氨基阴离子等价物被π-烯丙基钯亲电试剂截获以产生取代的高烯丙基胺。

  Structure-Activity Study of Tripeptide Thrombin Inhibitors Using .alpha.-Alkyl Amino Acids and Other Conformationally Constrained Amino Acid Substitutions

  摘要：

  In our continuing effort to design novel thrombin inhibitors, a series of conformationally constrained amino acids (e.g. alpha-alkyl, N-alkyl cyclic, etc.) were utilized in a systematic structure-activity study of the P3, P2, and P1 positions of tripeptide arginal thrombin inhibitors. Early examples of this effort include: D-MePhe-Pro-Arg-H (15), Boc-D-Phg-Pro-Arg-H (18), D-1-Tiq-Pro-Arg-H (23, D-1-Tiq D-1,2,3,4-tetrahydroisoquinolin-1-ylcarbonyl), and Boc-D-Phe-Pro-Arg-H (25).(10a,20) The current work clarifies the contribution of each residue of the tripeptide arginals toward the potent and selective inhibition of thrombin relative to that of t-PA and plasmin. The alpha-methylarginal modification in the P1 residue resulted in analogs 30 (D-MePhe at P3) and 32 (D-1-Tiq at P3) which had lower potency toward thrombin while exhibiting improved selectivity. Analogs modified at the P2 site were found to be very sensitive to the conformational changes induced by variations in side chain ring size with the flexible pipecolinic acid 31 being 2 orders of magnitude less potent at thrombin inhibition than the conformationally constrained azetidine analog 20. Examination of the P3 binding region indicated that alpha-alkylphenylglycine residues resulted in a tendency to exhibit substantial improvements in selectivity over the nonalkylated residues. Combinations of optimal P3 and P2 changes led to compounds TFA-D-Phg(alpha Et)-Azt-Arg-H (16), TFA-D-Phg(alpha Me)-Azt-Arg-H (17), Ac-D-Phg(alpha Me)-Azt-Arg-H (21), TFA-D-Phg(alpha Me)-Pro-Arg-H (27), 30, and 32, which are clearly more selective for thrombin versus plasmin than the nonconformationally constrained compounds.
