  摘要：

  Full details are presented for use of the Bsmoc amino-protecting group for both solid phase and rapid continuous solution syntheses. Application to the latter methodology represents a significant improvement over the corresponding Fmoc-based method for rapid solution synthesis due to the opportunity to use water or saturated sodium-chloride solution rather than an acidic phosphate buffer to remove all byproducts, with consequent cleaner phase separation and higher yields of the growing peptide. Comparison of the Bsmoc and Bspoc functions showed that the former, because of steric hindrance, does not suffer from the competitive or premature deblocking observed with the Bspoc system. Because of its incorporation of a styrene chromophore, resin loading of Bsmoc amino acids could be followed as has previously been shown for the Fmoc analogues. Applications of Bsmoc chemistry to peptide sequences incorporating the base sensitive Asp-Gly unit gave less contamination due to aminosuccinimide formation than comparable syntheses involving standard Fmoc chemistry because a weaker or less concentrated base could be used in the deblocking step. Experimental details are presented for building up peptides in solution via the continuous methodology. Deblockings involved the use of insoluble piperazino silica as well as the polyamine TAEA which simplified aqueous separation of the growing, but nonisolated peptide product, from excess acylating agent and other side products formed in the deblocking process. By the appropriate choice of base, one can act selectively at either site of a molecule which incorporates both beta-elimination and Michael acceptor sites as protective units (Bsmoc vs Fm and Fmoc vs Bsm).

  Diphenylphosphoryl azide (DPPA) mediated one-pot synthesis of Nα-Fmoc/Bsmoc/Boc/Z-protected ureidopeptides and peptidyl ureas as well as phenyl/succinimidyl (Nα-urethane protected) methyl carbamates starting from Nα-protected amino acids is reported. The formation of an azide, its rearrangement and coupling with an amino component is accomplished in a sequence of one-pot operations. The protocol has

  日期：2006.12

  The Goldschmidt-Wick type reaction between isocyanates of N-alpha-Fmoc-amino acids/peptide acids and N-alpha-Boc-/Z-/ Bsmoc-amino acids catalyzed by DMAP leads to the incorporation of a reversed peptide bond. It was found to be a simple, efficient and clean reaction. All the retro-inverso peptides made were obtained as crystalline compounds in 70-92% yields. (c) 2006 Elsevier Ltd. All rights reserved.

  A simple and racemisation-free synthesis of N-urethane protected α-amino/peptidyl alcohols by the reduction of the corresponding easily accessible N-acylbenzotriazoles is described. The method is practical, straightforward, fast and efficient for the synthesis of amino/peptidyl alcohols. All the alcohols made were isolated in high yields and purity.
