  Building Functionalized Peptidomimetics:  Use of Electroauxiliaries for Introducing N-Acyliminium Ions into Peptides

  摘要：

  A series of silyl-substituted amino acids have been synthesized, inserted into peptides, and then employed as precursors for oxidatively generating reactive N-acyliminium ions. Both electrochemical and chemical oxidation procedures have been employed. N-Acyliminium ion generation in a solid-phase substrate as well as application to a small library of functionalized dipeptides has been demonstrated. Limitations in terms of how electron-rich the silyl groups can be as well as the compatibility of multiple silyl groups within a longer peptide are defined.

  have been accessed through a novel enantioselective domino process. Lewis acid activation and organocatalysis were combined to generate the products from readily available substances. A new chiral amine catalyst ensures high enantiomeric ratios. Both enantiomers of the product can be derived and the configuration on the newly generated stereo centers were unambiguously related to the chirality of the

The resulting second-order rate constants k2 followed the correlation log k2(20 °C) = sN(N + E), where electrophiles are characterized by one parameter (E) and nucleophiles are characterized by the two solvent-dependent parameters N and sN. In this way, the organocatalysts A1-A32 were integrated in our comprehensive nucleophilicity scale

  N-Alkylated (S)-7-halogen-5-[1-(2-methoxymethylpyrrolidinyl)sulfonyl]isatins were developed as a new group of nonradioactive reference compounds for future radiotracers. Inhibitor potency studies of these compounds suggest that the binding pockets readily accommodate both the 7-halogen substituents and aliphatic side chains (methyl to n-butyl) as well as some ω-fluorinated analogues (3-fluoropropyl
