Hänschs
Hänschs refers to a family of chemical reactions in organic chemistry, most notably the Hänsch pyrrole synthesis and the Hänsch dihydropyridine synthesis. These named reactions are named after the German chemist Arthur Hantzsch.
The Hänsch pyrrole synthesis involves the reaction of an alpha-haloketone with a beta-ketoester in the presence
The Hänsch dihydropyridine synthesis is perhaps the more commonly referenced reaction. It involves a multi-component reaction
