Recommanded Product: 5-Methoxy-1H-indole-2-carbaldehyde. 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: 5-Methoxy-1H-indole-2-carbaldehyde, is researched, Molecular C10H9NO2, CAS is 21778-81-4, about One-pot asymmetric synthesis of quaternary pyrroloindolones through a multicatalytic N-allylation/hydroacylation sequence. Author is Lu, Hong; Lin, Jun-Bing; Liu, Jin-Yu; Xu, Peng-Fei.
An intramol., quaternary-C-center-forming hydroacylation of α-substituted acrylates was discovered. This interesting transformation can be readily incorporated into a multicatalytic tandem process enabled by a combination of nucleophilic tertiary amine and N-heterocyclic carbene catalysis. With no addnl. stoichiometric base required, this transformation affords quaternary pyrroloindolones with high levels of enantioselectivity.
