Studing on samarium diiodide promoted asymmetric intramolecular reducing coupling reactions, we have made the resolution of the racemic biaryl dials by using enantiomeric N-tert-butanesulfinamine as the resolving reagent successfully and thus obtained a series of axially chiral biaryl dials with high enantiomeric excess.

中文摘要在二碘化钐促进的分子内不对称还原偶联反应中，我们不仅对联芳基二醛底物的合成路线进行了优化，还发现N-叔丁基亚磺酰胺辅基可以作为手性试剂，成功地对联芳基骨架二醛化合物进行拆分，得到高对映体过量的轴手性二醛类化合物。

To investigate the expression, location and function, long distance PCR was used to expand the targets containing open reading frame. The expressive vectors of prokaryotic and eukaryotic cells were constructed after product purification and connecting with vectors. The prokayotic vectors were induced to express the protein by IPTG and the protein was seen by denaturalization PAG electrophoresis and dyeing. The eukayotic expressive vectors were transfected into culture cells and the protein was found in the nulceolus under the observation of the confocal microscope. The transfected cells were chosen by the geneticin (G418). The cell cyele was examined by flow cytometer and the cell numbers were reduced obviously in the stage of G〓-G〓 and G〓-M, but increased distinguishably in the S stage.
