overcome in the second route, which involved reductive amination of 2,3:4,5-di- O -isopropylidene- aldehydo -β- d - arabino -hexos-2-ulo-2,6-pyranose; following a deblocking step, N -(1-deoxy- d -fructos-1-yl) derivatives of the aforementioned amino acids were obtained in yields which were at least double those reported for the current procedure involving the reaction of an amino acid with d -glucose, and
摘要描述了两种合成1-缬氨酸,1-亮氨酸,1-甲硫氨酸,1-苯丙氨酸和6-氨基己酸的N-(1-脱氧d-果糖-1-基)衍生物的途径。一种途径涉及在氰基硼氢化钠存在下对d-阿拉伯糖-己基-2-己糖的还原胺化。产量受到难以去除的大量N-(1-脱氧己糖醇-1-基)氨基酸形成的限制。在第二种方法中克服了这一缺点,该方法涉及2,3:4,5-二-O-异亚丙基-醛-β-d-阿拉伯糖-己二-2-ulo-2,6-吡喃糖的还原胺化。在去封闭步骤之后,获得上述氨基酸的N-(1-脱氧-d-果糖-1-基)衍生物,其收率至少是目前涉及氨基酸与d的反应的报道方法的两倍。 -葡萄糖,
