Treatment of the readily available (S)-(+) and (R)-(-)-2-aminobutan-1-ol 1 with sodium hydride followed by benzyl chloride, or a substituted benzyl halide, afforded the corresponding -benzyl bases 2-5 in high yields. These new bases are recommended for the large scale resolution of racemic acids. For instance, they proved efficient for the practical resolution of -acetylphenylglycine (±)-7, -acety
用氢化钠然后用苄基氯或取代的苄基卤处理易得的(S)-(+)和(R)-(-)-2-氨基丁-1-醇1,得到相应的-苄基碱2 -5高产。建议将这些新碱用于大规模拆分外消旋酸。例如,事实证明它们对于-乙酰基苯基甘氨酸(±)-7,-乙酰基- (4-羟苯基苯基)甘氨酸(±)-9和-氯乙酰基- (4-羟苯基)甘氨酸(±)-10的实际拆分有效。
