Abstract
This review described the preparation of 2-chloroquinoline-3-carbaldehyde derivatives through Vilsmeier-Haack formylation of N-arylacetamides and their use as a key intermediate for the preparation of 2-aminoquinoline-3-carbaldehydes. The synthesis of the 2-aminoquinolines can be done through the following chemical reactions: Claisen-Schmidt condensation, 1, 3-dipolar cycloaddition, one-pot multicomponent reactions (MCRs), and reductive amination.
Keywords: 2-chloroquinoline-3-carbaldehyde, 2-aminoquinoline-3-carbaldehydes, Vilsmeier-Haack, synthesis, reactivity, reductive animation.
