SDS of cas: 21778-81-4. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5-Methoxy-1H-indole-2-carbaldehyde, is researched, Molecular C10H9NO2, CAS is 21778-81-4, about Asymmetric construction of polycyclic indole derivatives with different ring connectivities by an organocatalysis triggered two-step sequence. Author is Xie, Chao-Chao; Tan, Rui; Liu, Yan-Kai.
An organocatalysis triggered highly regio- and stereoselective two-step sequence between hemiacetals and indole-containing nitroolefins was developed. The key to the success of this sequence was the intramol. oxocarbenium ion induced collective alkylation at the C3, C2, or N1-position of the indole moiety, resp., providing biol. important polycyclic indole derivatives with different ring connectivities. An unexpected epimerization was observed during the C3-alkylation process, which generated products with different relative configurations compared with the C2- and N1-alkylation products.
This literature about this compound(21778-81-4)SDS of cas: 21778-81-4has given us a lot of inspiration, and I hope that the research on this compound(5-Methoxy-1H-indole-2-carbaldehyde) can be further advanced. Maybe we can get more compounds in a similar way.
