Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 921-60-8, Name is L-Glucose, SMILES is O=C[C@H]([C@@H]([C@H]([C@H](CO)O)O)O)O, in an article , author is Yang, Ke, once mentioned of 921-60-8, Name: L-Glucose.
A novel upper-rim functionalized calix[4]squaramide organocatalyst bearing bis-squaramide and cyclohexanediamine scaffolds was designed and prepared to catalyse a serial of asymmetric Michael addition of 1,3-dicarbonyl compounds to alpha,beta-unsaturated carbonyl compounds in high yields (up to 99 %) and good to excellent enantiomeric excesses (up to 99% ee). The comparative experiments indicated that the cooperative effect between calixarenes cavitives and chiral catalytic centers on this calix[4]squaramide catalyst could promote these reactions. Moreover, this strategy also provides valuable and easy access to chiral chromene, naphthoquinone and acetylacetone derivatives, which are important skeletons in biological and pharmaceutical compounds.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 921-60-8, you can contact me at any time and look forward to more communication. Name: L-Glucose.
