  The direct conversion of various carboxylic acids, that include sterically hindered amino acids and di-peptides, to O-benzyl hydroxamates is demonstrated using sulfonate esters of benzotriazoles under ambient and milder conditions without significant racemization. This simple and efficient protocol is extended to the synthesis of O-benzyl hydroxamates, using in situ generated solid supported TsOBt

  A series of tripeptidyl analogues carrying hydroxamic acid residue at the C-terminus of the molecule were synthesized, and their inhibitory activities against vertebrate collagenase and other metalloenzymes including bacterial collagenase were examined. Both Z-Pro-Leu-Ala-NHOH and Z-Pro-D-Leu-D-Ala-NHOH showed highly specific and potent inhibitory activity against tadpole and human skin collagenases with an IC50 of 10-6 M order.
