Optically active 2-aminoalkan-1-ols in the form of their O-acyl-N-trifluoroacetyl derivatives have been resolved by g.l.c. with N-dodecanoyl-L-valine 6-undecylamide (1) as the stationary phase. A bulky O-acyl group substantially facilitates resolution. Resolutions of the N-trifluoroacetyl-esters of α-, β-, and γ-amino-acids on diamide phases are also reported. The order of emergence of the derivatives
以O-酰基-N-三氟乙酰基衍生物形式存在的旋光2-氨基烷-1-醇已通过使用N-十二烷酰基-L-缬氨酸6-十一烷基酰胺(1)作为固定相的glc拆分。庞大的O-酰基基团大大促进了拆分。还报道了二酰胺相上α-,β-和γ-氨基酸的N-三氟乙酰基酯的拆分。在L-异构体之后,2-氨基烷-1-醇和γ-氨基酸的衍生物的出现顺序为D,即与α-氨基酸相反。
