  Head-to-Tail Dimerization and Organogelating Properties of Click Peptidomimetics

  摘要：

  Click triazole-based ollgopeptides 1-3 were found to self-dimerize (K-dim approximate to 10-680 M-1) In a head-to-tail fashion based on H-1 variable concentration, 2D, and HID exchange NMR, VPO, CD, FT-IR studies and Gaussian 03 simulations. The dimerization constant K-dim was shown to increase with increasing number of the amino acid units. Within the same oligomeric series, the K-dim, value is strongly affected by the size of the C-terminal end group. The tripeptides 2 are also excellent organogelators of aromatic solvents.

  A smooth traceless ligation strategy using an air-stable phosphane probe (2-(diphenylphosphanyl)phenyl)methanol as a C-terminus activator has been demonstrated at simple and sterically hindered amino acid junctions (Gly, Ala, Trp, Glu). This Staudinger peptide ligation proceeds via formation of a seven-membered transition state to afford di-, tetra-, and pentapeptides in 78–95% yields. The experimental

  在简单且空间受阻的氨基酸连接处（Gly，Ala，Trp，Glu）已证明使用空气稳定的膦探针（2-（二苯基膦基）苯基）甲醇作为C末端活化剂的平稳无痕连接策略。这种Staudinger肽的连接通过形成七元过渡态而进行，以78％至95％的产率提供二，四和五肽。通过计算计算，从理论上研究了Gly连接处的连接和Glu连接处的区域选择性连接的实验结果。这些发现建立了我们合成的膦探针用于Staudinger肽连接的通用行为，以合成所选的肽和蛋白质。

  The design and synthesis of a new diazotransfer reagent, imidazole-1-sulfonyl azide hydrochloride, are reported. This reagent has proven to equal triflyl azide in its ability to act as a "diazo donor" in the conversion of both primary amines into azides and activated methylene substrates into diazo compounds. Crucially, this reagent can be prepared in a one-pot reaction on a large scale from inexpensive
