Allylic Substitution Under mild conditions, allylic carbonates can be borylated by treatment with bis(pinacolato)diboron in the presence of a copper catalyst to give the corresponding allyl boronates.5 Using a chiral ligand, excellent enantioselectivities were obtained.6 Borylation of Aldehydes Treatment...
Two major classes of hydroxy fatty acids are formed by hydroxylation of the omega-side chain and by hydroxylation of bisallylic methylene carbons. Bisallylic cytochrome P450-hydroxylases transform linoleic acid to 11-hydroxylinoleic acid, arachidonic acid to 13-hydroxyeicosa-5Z,8Z,11Z,14Z-tetra...
Hence, the nucleophile can attack a variety of carbons, produce a range of products, and as a result, reduce the yield and ee of the products. Conclusion In summary, asymmetric copper catalyzed allylic C-H bond oxidation of cyclic and acyclic alkenes with a series of substituted t-butyl ...
Desirably, the wax composition is curable so as to participate in the curing of the ink. Suitable examples of curable waxes include those that are functionalized with curable groups. The curable groups may include, for example, acrylate, methacrylate, alkene, allylic ether, epoxide and/or oxetane...
