bis-alpha-amino acids was developed. The synthesis of omega-trityloxy delta,epsilon-unsaturated alpha-amino acids was based on the Wittig reaction of methyl (2S)-2-[bis(tert-butoxycarbonyl)amino]-5-oxopentanoate with omega-trityloxy alkylidene triphenylphosphoranes. After hydrogenation, the omega-hydroxy alpha-amino acid was used as starting material for the synthesis of other omega-functionalized alpha-amino
开发了合成对映体纯的ω-羟基,ω-羧基,ω-氧代和ω-氨基α-氨基酸和双-α-氨基酸的有效途径。ω-三苯甲基氧基δ,ε-不饱和α-氨基酸的合成是基于(2S)-2- [双(叔-丁氧基羰基)氨基] -5-氧戊酸甲酯与ω-三苯甲基氧基亚烷基三苯基膦的Wittig反应。氢化后,将ω-羟基α-氨基酸用作合成其他ω-官能化的α-氨基酸的原料。α-氨基酸或双-α-氨基酸的侧链的长度取决于用于制备膦烷的原料链烷二醇或二溴化物。
