Safety of 2-Amino-5-chlorobenzaldehyde. 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: 2-Amino-5-chlorobenzaldehyde, is researched, Molecular C7H6ClNO, CAS is 20028-53-9, about A facile one-pot synthesis of 2-substituted-3-aminoquinolines: preparation of benzo[b]naphthyridine-3-carbonitriles. Author is Wang, Yanong D.; Boschelli, Diane H.; Johnson, Steven; Honores, Erick.
A facile one-pot synthesis of 3-aminoquinolines from ortho-aminobenzaldehydes was developed. Et 6,7-dimethoxy-3-aminoquinoline-2-carboxylate, a key intermediate for the preparation of a 4-anilino-benzo[b][1,5]-naphthyridine-3-carbonitrile, was efficiently prepared by this method. Synthetic routes to 4-anilino-benzo[b][1,5]-naphthyridine-3-carbonitrile and 4-anilino-benzo[b][1,8]-naphthyridine-3-carbonitrile are described.
After consulting a lot of data, we found that this compound(20028-53-9)Safety of 2-Amino-5-chlorobenzaldehyde can be used in many types of reactions. And in most cases, this compound has more advantages.
