N-o-Nitrophenylsulfenylamino acid amides of glycine, alanine (DL and L), leucine (DL and L), methionine (DL), phenylalanine (DL and L), and proline (L) were dehydrated in POCl3-pyridine. The N-protected α-amino-nitriles obtained were treated with anhydrous HCl affording the corresponding α-aminonitrile hydrochlorides. The optical purity of the L-α-aminonitriles was well retained.
甘氨酸、丙氨酸(DL 和 L)、亮氨酸(DL 和 L)、甲硫氨酸 (DL)、苯丙氨酸 (DL 和 L) 和脯氨酸 (L) 的非硝基苯硫基氨基酸酰胺在 POCl3-吡啶中脱水。得到的 N-保护的 α-氨基腈用无水 HCl 处理,得到相应的 α-氨基腈盐酸盐。L-α-氨基腈的光学纯度保持良好。
