improved, stereoselective synthesis of the natural, non-proteogenic amino acid L-alanosine has been developed, starting from the readily available and cheap substrate L-serine, in six steps and 49% overall yield. The process is very efficient, is suitable for large-scale production, and affords L-alanosine with properties comparable with those of the natural substance. In addition, the structural assignment
已开发出一种改进的立体选择性合成天然非蛋白质氨基酸 L-丙氨酸,从容易获得且廉价的底物 L-丝氨酸开始,分六步进行,总产率为 49%。该工艺非常高效,适合大规模生产,并提供具有与天然物质相当的特性的L-丙氨酸。此外,关于一些先前报道的天然氨基酸的合成烷基化衍生物的结构归属已得到明确证实。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
