of neutral amino acids, such as glycine. L-alanine, DL-alanine, L-valine, DL-valine, L-leucine, L-phenylalanine, and L-tyrosine, were prepared by the catalytic reductive condensation of the corresponding amino acids with formaldehyde. The N-oxides were satisfactorily synthesized by the oxidation of the N,N-dimethyl derivatives with an aqueous mixture of hydrogen peroxide and acetic acid. The reaction
中性氨基酸的 N,N-二甲基衍生物,如甘氨酸。L-丙氨酸、DL-丙氨酸、L-缬氨酸、DL-缬氨酸、L-亮氨酸、L-苯丙氨酸和 L-酪氨酸是通过相应氨基酸与甲醛的催化还原缩合制备的。N-氧化物通过用过氧化氢和乙酸的含水混合物氧化 N,N-二甲基衍生物而令人满意地合成。给出了反应条件、分析数据和产物的一些性质。
