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 NaBH4 splitting of the Se–Se bond in commercial
报道了新型的非天然二氨基酸,2-氨基-3-[(2'-氨基烷基)硒代]丙酸或Se-(氨基烷基)硒代半胱氨酸的一般合成。在设计的条件下,将对映体纯的N -Boc保护的β-1-碘胺(很容易从蛋白质来源的α-氨基酸中产生),用由商业化的1-硒代半胱氨酸中Se-Se键分裂的NaBH 4裂解得到的硒酸阴离子处理。。Se-烷基化产物对映体纯,反应产率高(92-98%),没有任何可检测到的伴随副产物痕迹。
