α-Amino acids and α-amino methyl esters are easily converted to their N-monoalkyl derivatives by a reductive condensation reaction using several carbonyl compounds in the presence of sodium borohydride. This reducing agent has shown a wide versatility with minor but essential procedural variations. The reaction allows the α-monodeuterium labeling of the new N-substituent by use of sodium borodeuteride.Key words: α-amino acid, α-amino methyl esters, sodium borohydride, reductive N-monoalkylation, carbonyl compounds.
α-氨基酸和α-氨基甲酯可以通过还原缩合反应在存在苏打硼氢化钠的情况下,利用几种羰基化合物轻松转化为它们的N-单烷基衍生物。这种还原剂在轻微但必要的程序变化下显示出广泛的多功能性。该反应允许通过使用苏打硼氘化钠对新的N-取代基进行α-单氘标记。关键词:α-氨基酸,α-氨基甲酯,苏打硼氢化钠,还原性N-单烷基化,羰基化合物。
