    Efficient Acylation of the N-Terminus of Highly Hindered Cα,α-Disubstituted Amino Acids via Amino Acid Symmetrical Anhydrides
    摘要:
    GRAPHICSFmoc amino acid symmetrical anhydrides are efficient and readily available reagents for acylation of the N-terminus of highly hindered C-alpha,C-alpha-dialkylated alpha-amino acids. Comparison of a variety of coupling protocols showed that the symmetrical anhydride method always provided the superior results. This method was successfully applied to the solid-phase synthesis of a peptide containing three alphaalphaAAs at alternating positions.

  • Sterically Hindered <i>C</i><sup>α</sup><sup>,</sup><sup>α</sup>-Disubstituted α-Amino Acids:  Synthesis from α-Nitroacetate and Incorporation into Peptides

    demanding C(alpha,alpha)-dibenzylglycine (Dbg) has been incorporated into a peptide using solid-phase synthesis. It was found that once sterically congested Dbg is at the peptide N-terminus, further chain extension becomes very difficult using uronium or phosphonium salts (PyAOP, PyAOP/HOAt, HATU). However, preformed amino acid symmetrical anhydride couples to N-terminal Dbg in almost quantitative yield

  • Facile Synthesis of α,α-Diisobutylglycine and Anchoring Its Derivatives onto PAL-PEG-PS Resin
    作者:Yanwen Fu、Marcus A. Etienne、Robert P. Hammer
    DOI:10.1021/jo034885j
    日期:2003.12.1
    alpha,alpha-Diisobutylglycine has been synthesized using a Pd-mediated dialkylation of ethyl nitroacetate as a key first step. The free alphaalphaAA is N-alpha-protected and has been applied to the assembly of conformationally constrained peptide analogues. Mixed anhydrides from BOP-Cl and Fmoc-alphaalphaAA-OH are used for anchoring alphaalphaAAs onto a trialkoxybenzyl linker on PEG-PS grafted support, upon which a beta-strand mimic with difficult sequence is assembled in a superior quality.
