Popis: The general synthesis of a new class of non-natural diamino acids, 2-amino-3-[(2′-aminoalkyl)seleno]propanoic acids, or Se-(aminoalkyl)selenocysteines, is reported. Under the conditions devised, enantiopure N -Boc-protected β- l -iodoamines, which are readily generated from proteinogenic α-amino acids, were treated with the selenolate anion obtained from NaBH 4 splitting of the Se–Se bond in commercial l -selenocystine. The Se-alkylation products were enantiomerically pure and the reaction is high yielding (92–98%), without any detectable traces of accompanying by-products.
