Product Details of 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 Synthesis of indole-2-carbaldehydes, 2-(2-aminoethyl) – and 2-(2-aminopropyl)indoles. Author is Siddappa, S.; Bhat, G. A..
Et indole-2-carboxylate derivatives (e.g. I) were reduced by LiAlH4 to indole-2-methanol derivatives (e.g. II). These were oxidized by MnO2 to indole-2-carboxaldehyde derivatives (e.g. III), which were also prepared from the indole-2-carboxylates by the McFadyen-Stevens reaction. The aldehydes reacted with MeNO2 and EtNO2, and the condensation products (e.g. IV and V) were reduced by LiAlH4 to 2-(2-aminoethyl)indoles (e.g. VI) and 2-(2-aminopropyl)indoles (e.g. VII), resp.
