• CuI-Promoted One-Pot Synthesis of N-Boc Protected β-Ketotriazole Amino Acids: Application in the Synthesis of New Class of Dipeptidomimetics

  One-pot click chemistry of Nα-Boc-bromomethylketones, NaN3 and propiolic acid affords N-Boc protected 1,4- disubstituted 1,2,3-β-ketotriazole acids in good to excellent yield. The use of CuI as catalyst and DMSO as solvent leads the click reaction to efficient, practical and column-free preparation of the title compounds. The utility of the resulting unnatural amino acids as building blocks to prepare triazole possessing peptidomimetics is also delineated.

• Coupling N-Methylated Amino Acids Using PyBroP and PyCloP Halogenophosphonium Salts: Mechanism and Fields of Application

  PyBroP (1) and PyCloP (2), two halotripyrrolidinophosphonium hexafluorophosphates, are peptide-coupling reagents highly efficient for coupling N-methylated amino esters, in contrast with PyBOP (3), the hydroxybenzotriazolyl analogue. These halogenophosphonium salts 1 and 2 are convenient (one-pot reactions) stable solids soluble in conventional solvents. Use of them gave an excellent peptide yield with essentially no epimerization. Activation with these reagents probably involves the formation of an (acyloxy)phosphonium, as shown in the case of 2,4,6-trimethylbenzoic acid activation. In the case of reagents 1 and 2, oxazolone and/or a symmetrical anhydride were intermediates which were rapidly aminolyzed. In contrast, the benzotriazolyl ester intermediate which was formed with PyBOP (3) was poorly reactive with N-methylated amino esters. PyBroP (1) and PyCloP (2) were less efficient in the coupling of some Boc-amino acids because of N-carboxyanhydride formation; this was particularly the case when Boc-Val-OH or Boc-MeVal-OH was coupled with MeVal-OMe.
