Due to the configuration inversions of chiral carbon in the synthesis of side chain, we synthesized the corresponding optical isomer of doripenem for quality control.
由于在侧链的合成中,有手性碳原子发生了构型翻转,因此我们合成了一个相应的多利培南光学异构体,以利于质量控制。
Conclusion: There is no optical isomer in alliin samples. its configuration was found to be S-allyl-L-cysteine sulfoxide.
结论:国产蒜氨酸中无手性对映体杂质,其立体构型为S-烯丙基-L-半胱氨酸亚砜。
The raceme, the (R)-isomer and the (S)-isomer are identical in chemical structural formula but different in stereostructure and optical rotation performance.
外消旋体、(R)-异构体和(S)-异构体具有相同的化学结构式,具有不同的立体结构和旋光性能。
