A convenient and scalable synthesis of enantiomers of butane-2,3-diacetal-protected glyceraldehyde was accomplished from D-mannitol and L-ascorbic acid, respectively. The R-aldehyde was additionally converted to the (R,R)-butane-2,3-diacetal glycolic acid building block 1.
分别由 D-甘露醇和 L-抗坏血酸完成了方便且可扩展的丁烷-2,3-二缩醛保护的甘油醛对映异构体的合成。R-醛另外转化为 (R,R)-丁烷-2,3-二缩醛乙醇酸结构单元 1。
