Description
Technical Field
The invention belongs to the technical field of asymmetric organic synthesis, and particularly relates to a chiral spiro oxindole compound and a diastereoisomeric divergent preparation method thereof.
Background
The spiro oxindole compound widely exists in natural products and drug molecules, has broad-spectrum biological activity, has great significance in drug development due to efficient construction, and is widely paid attention to chemists and pharmacists. In recent years, the highly stereoselective synthesis of chiral spiro oxindoles by asymmetric catalysis has gradually become a focus of research by organic chemists.
Chiral is one of the essential attributes of nature, and a large number of chiral molecules are stored in nature and living bodies, and many biological macromolecules such as proteins, polysaccharides, nucleic acids and the like which are important bases of life activities basically have chirality. Chiral research plays an important role in life science, pharmacy and food science. There are significant differences in pharmacology and toxicity of chiral drugs, such as thalidomide (also known as reaction arrest), which has been widely used as a sedative in europe, and many pregnant women produce abnormal fetuses after taking this drug because only the R-isomer is sedating and the S-isomer is teratogenic. The development of a novel, rapid, efficient and sensitive chiral separation analysis method has very important significance for the stereoselective synthesis of enantiomers, pharmacological research of chiral medicaments, purity analysis of enantiomers, environmental monitoring and healthy life of human beings. Thus, developing new synthetic methodologies to achieve the acquisition of all stereoisomers of fragments with multiple chiral elements is a highly challenging field with significant scientific research value.
The cooperative control strategy of the double catalytic system has proved to be a simple and effective solution. In recent years, chemists develop various types of cooperative control strategies successively, so that three-dimensional divergent synthesis with diversified structure types is realized efficiently, and under unified raw materials, synthesis routes and reaction conditions, collective asymmetric synthesis of multiple diastereomers of the multi-chiral center molecule is realized accurately and controllably, thereby providing important guarantee for synthesis of multiple chiral isomers of important physiologically active natural products and research on pharmacodynamic relations.
The wide application of chiral spiro oxindole compounds has prompted us to find a high-efficiency synthesis method for realizing different isomers of the compounds. However, no diastereoselective synthesis of chiral spiro oxindole derivative compounds has been reported. Therefore, there is an urgent need to develop a general strategy for diastereoselective synthesis of chiral spiro oxindole compounds with high yield and high enantioselectivity, which is realized in a precise and rapid manner, starting from a simple and easily available framework.

Example 23: test of Activity of four isomers of chiral spirooxindole Compounds 3aa, 3ba and 3ab on HeLa cells
HeLa cells were cultured in DMEM dishes containing 10% fetal bovine serum and 100units/ml penicillin+100. Mu.g/ml streptomycin. Four stereoisomers of compounds 3aa, 3ba and 3ab were screened at a concentration of 5 μm to test changes associated with chromosomal mismatches during mid-front and late onset of HeLa cells. Each compound inhibited mitosis, with (R, S) -3aa, (R, S) -3ba and (R, S) -3ab being most pronounced.
Example 24: imaging test of chiral spirooxindole Compounds (R, S, S) -3aa, (R, S, S) -3ba and (R, S, S) -3ab on Hela cell Activity
For time-lapse imaging, heLa cells were cultured in glass bottom dishes (MatTek) and transfected with mCherry-H2B and GFP-Tubulin to reveal chromosomes and microtubules. The plasmid was purified with a purification kit (QIAGEN) and cells were transfected with Lipofectamine 3000 (Invitrogen). Cells were added to carbon dioxide free medium (Gibco) with 10% fetal bovine serum and 2mM glutamine. Before imaging for 1 hour, 5. Mu.M of the corresponding compound in dimethyl sulfoxide was added, and the control group was added with dimethyl sulfoxide. During imaging, the dishes were placed in a sealed chamber at 37 ℃. Live cell images were taken every 3 minutes using a DeltaVision microscope system and deconvolved, and the resulting images were as follows. From the images, it can be concluded that the mitosis process of Hela cells of the experimental group is significantly slower compared with the control group, i.e. the chiral spiro oxindole compounds (R, S) -3aa, (R, S) -3ba and (R, S) -3ab all have a significant inhibitory effect on the mitosis process of Hela cells.
