  Structure of Phosphorus-Containing Peptide Ligands. X-ray and NMR Structural Study of Free Ligand and Rhodium Complex

  摘要：

  The structure of a series of phosphorus-containing peptides was studied, The X-ray structure of a phosphorus-containing dodecapeptide is reported. Analysis of the solution structure of similar phosphorus-containing peptides before and after coordination of rhodium is also reported. In both the solid state and in solution, the peptides were found to exist in a mixture of a-helical and 3(10) helical conformations. Coordination of rhodium to the i, i + 4 orientated phosphine groups appears to alter the conformational preference.

  基于天然产物Gramicidin S的双膦功能化环十肽：过渡金属配位的潜在支架

  摘要：

  天然产物Gramicidin S是新型寡肽双膦配体的有前途的支架，将有利的刚性手性骨架与膦取代基紧密结合在一起。通过一种涉及手性镍席夫碱模板的对映选择性烷基化的新方案，合成了所需的非天然的，含膦的氨基酸构件。制备了三个Ni配合物，其中膦基和掺入的甘氨酸的α-碳原子之间具有不同的烷基链；其中两个的绝对立体化学是通过单晶X射线结构分析确定的。通过分离模板，对映体L膦氨基酸使固相，逐步构建膦修饰的寡肽的线性序列成为可能。在环化过程中，产生了三个双膦取代的Gramicidin S类似物，只是膦基和寡肽骨架之间的连接大小和形状不同。它们的晶体结构表明这些物质具有作为螯合配体的潜力。

  We have been actively involved in the development of parallel approaches for the discovery of phosphine ligands. Our approach has been based on the incorporation of phosphine-containing amino acids into peptide sequences that are designed to have stable secondary structures. We have examined helical and turn secondary structures and have reported that alkylation of cyclopentenyl acetate with dimethylmalonate can be catalyzed in high enantiomeric excess (ee) with a beta-turn-based ligand. The importance of the peptide secondary structure was demonstrated through the synthesis of a series of peptide ligands where the nature of the turn-forming residues was probed. Additionally, other turn-forming units and a variety of different phosphine-containing amino acids have been examined for their ability to control the selectivity of the allylation reaction. This paper reports the results obtained through the examination of different turn motifs as well as different phosphine substitutions on the "best" turn sequence, Pps-Pro-D-Xxx-Pps.
