Chirality is a common phenomenon in nature,and many natural products and active ingredients of pharmaceuticals have chiral structural units.Through asymmetric catalytic strategies,chiral molecules can be synthesized to address relevant needs in pharmaceuticals and other areas.At the current undergraduate teaching level,knowledge about asymmetric catalysis only focus on the basic concepts and judgment methods of chirality,while neglecting how to construct chiral molecules.Therefore,it is an important direction to supplement modern experimental teaching content of organic chemistry by effectively integrating the frontier hot topics of the discipline into undergraduate experimental teaching and expanding the scope of undergraduate experimental teaching.Taking the asymmetric synthesis of α-hydroxy-β-keto acid esters under visible light irradiation as an entry point,this experiment is intended to effectively combine the two frontier topics of organophotochemistry and asymmetric catalysis,and apply them to undergraduate experimental teaching.Through this experiment,on the one hand students can understand the frontier knowledge and enhance their interest in organic chemistry,and on the other hand learn the operations of thin layer chromatography,flash column chromatography and the related instruments.In addition,students will be able to apply the theoretical knowledge to the actual structural analysis,and to exercise their subjective initiative,improve their practical capability and enhance their awareness of environmental protection.

The study of intangible cultural heritage has been gaining increasing attention year by year, with various theories emerging. However, there is still a lack of in-depth exploration and scientific popularization of the scientific principles embedded in intangible cultural heritage. This experiment, driven by a commitment to cultivating the fertile ground of intangible heritage and infusing traditional culture with the charm of technology, aims to simulate traditional ceramic glazing techniques and decode the scientific principles behind the ever-changing colors of porcelain glazes. Focusing on three aspects involving preparation of ceramic glaze pigments, glaze surface decoration techniques, and the glaze discoloration process, the experiment replaces professional materials with common household items and substitutes high-temperature firing with room-temperature reactions. This approach not only achieves a demonstration of glaze discoloration at room temperature but also faithfully replicates the processes of overglaze, underglaze, and doucai (multi-colored decoration) in traditional porcelain glaze decoration. Furthermore, the virtual simulation programs has been developed, integrating online and offline platforms to promote a multi-dimensional and gradient approach to the scientific popularization of traditional ceramic techniques.
