Quality Control of Mesitylcopper(I). The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about In situ Catalytic Generation of Allylcopper Species for Asymmetric Allylation: Toward 1H-Isochromene Skeletons. Author is Kawai, Junya; Chikkade, Prasanna Kumara; Shimizu, Yohei; Kanai, Motomu.
Allylcopper species can be generated in situ via catalytic intramol. oxycupration of allenic alc. The allylcopper can react with various aldehydes and a ketone to give 1H-isochromene derivatives enantioselectively. The protocol is atom-economical, highly regioselective, stereoconvergent, and tolerant to free OH groups. Thus, e.g., enantio- and regioselective oxycupration/asym. addition cascade reaction of allenic alc. I with benzaldehyde in presence of mesitylcopper and chiral diphosphine ligand in HMPA/THF afforded isochromene II (98% yield, 92% ee).
