- The
Blaise reaction is an
organic reaction that
forms a β-
ketoester from the
reaction of zinc
metal with an α-bromoester and a nitrile.[1][2][3] The reaction...
- The Conrad–Limpach
synthesis is the
condensation of
anilines (1) with β-
ketoesters (2) to form 4-hydroxyquinolines (4) via a
Schiff base (3). The overall...
- Synthesis,
named for
Arthur Rudolf Hantzsch, is the
chemical reaction of β-
ketoesters (1) with
ammonia (or
primary amines) and α-haloketones (2) to give substituted...
