Notes:
Triphenylantimony bis(aminoacylate)s [Ph3Sb(O—A)2, A = Z—Gly, Z—Phe, Z—Leu, Bz—Phe] were prepared by direct condensation between triphenylstibine oxide and N-protected amino-acids in acetone. The aminolysis of these antimony aminoacylates by amino-acid esters gave corresponding dipeptides, which lead to a catalytic dipeptide synthesis using triphenylstibine oxide as a catalytic precursor of the antimony aminoacylate in situ.
