A new method for the stereoselective synthesis of optically pure β,γ-unsaturated α-amino acids in L or D configuration is developed by reacting the dilithiate of (2R)-2-Bocamino-3-phenylsulfonyl-1-(2-tetrahydropyranyloxy)propane 1 or its (2S)-antipode 2, both derived from L-serine, with aldehyde, followed by stereoselective olefin formation, desulfonylation and oxidation.
通过使(2R)-2-Bocamino-3-phenylsulfonyl-1-(2-tetrahydropyranyloxy)的二锂盐反应,开发了一种立体选择性合成L或D构型的光学纯β,γ-不饱和α-氨基酸的新方法。均由L-丝氨酸衍生的丙烷1或其(2S)-阴离子2与醛,然后形成立体选择性烯烃,进行脱磺酰基和氧化反应。
