Anwendungsbeispiele Englisch
  • The synthesis uses such reactions as the Mannich reaction, Pictet-Spengler reaction, the Curtius rearrangement, and chiral rhodium-based diphosphine-catalyzed enantioselective hydrogenation.
  • The prevalence of β-carboline alkaloids is associated with the ease of forming the β-carboline core from tryptamine in the intramolecular Mannich reaction.
  • It undergoes Friedel-Crafts acylation with acetyl chloride and aluminium chloride to give the acyl derivative 2, with formaldehyde and hydrochloric acid to the chloromethyl derivative 3, in a Vilsmeier-Haack reaction with N-methylformanilide and phosphorus oxychloride to the formyl 4, and in a Mannich reaction to amine derivative 5.
  • A Mannich reaction with dimethylamine and formaldehyde gives β-dimethylaminopropiophenone. Using diethylamine instead gives the diethylamino analog.
  • This reaction is related to the Eschweiler–Clarke reaction, in which amines are methylated to tertiary amines, the Leuckart–Wallach reaction, or by other amine alkylation methods such as the Mannich reaction and Petasis reaction.

  • The Mannich reaction was named after his discovery of the mechanism in 1912.
  • This reaction is described as an intramolecular "double Mannich reaction" for obvious reasons. It is not unique in this regard, as others have also attempted it in piperidine synthesis.
  • The added carbonyl is later converted to a terminal alkene via a Wittig reaction, allowing for the key tertiary nitrogen and the pentacyclic core to be formed via an aza-Cope-Mannich reaction.
  • Amination can occur in a number of ways including reaction with ammonia or another amine such as an alkylation, reductive amination and the Mannich reaction.
  • An integral component of the Mannich reaction, in addition to an amine and a carbonyl compound, is a carbanion, which plays the role of the nucleophile in the nucleophilic addition to the ion formed by the reaction of the amine and the carbonyl.

  • The Mannich reaction of 2-butanone (1) with formaldehyde and dimethylamine gives 4-Dimethylamino-3-methyl-2-butanone [...] (2).
  • Aldol condensation of the side chain carbonyl group with the doubly activated ring methylene group would then result in cyclization to pyrrole 5; simple tautomeric transformation would then give the observed product. Mannich reaction of 6 with formaldehyde and morpholine gives the tranquilizer molindone (7).
