Pomeranz-Fritsch Reaction is acid-catalyzed Synthesis of isoquinoline by heatingcyclization of benzalaminoacetals (these are Schiff bases) to give substituted isoquinolines is known as the Pomeranz-Fritsch reaction.
Baker-Venkataraman Rearrangement is the base-promoted (KOH) rearrangement of aromatic 2-acyloxy ketones to the corresponding aromatic 1,3-diketone (β-diketones)
This transformation is referred to as the Prilezhaev reaction for synthesis of oxiranes (epoxides) from isolated double bonds by using peroxycarboxylic acids as oxidizing agents. This method provides products in racemic mixture form.
The formation of oxacyclic and carbocyclic ring systems by terminating Prins cyclizations with the pinacol rearrangement in a tandem fashion is known as the Prins-pinacol rearrangement.
The Reimer-Tiemann reaction is an organic transformation that converts a phenol into an 2-hydroxy benzaldehyde using chloroform, a base, and an acid work-up at last step. Reimer-Tiemann Reaction Mechanism: The reaction commences with removing a proton from chloroform by the base, forming a trichlorocarbanion. This intermediate, however, spontaneously eliminates a chloride ion, generating a neutral … Read more
Burgess Reagent Mechanism, E.M. Burgess discovered that 2o and 3o alcohols could be dehydrated with the inner salt of (methoxycarbonylsulfamoyl)triethylammonium hydroxide the reagent is called the Burgess reagent to afford the corresponding olefins through intramolecular elimination reaction. This process is now known as the Burgess dehydration reaction. Burgess Reagent: Burgess Reagent cas : 29684-56-8 Synonym(s): Methyl N (triethylammoniosulfonyl)carbamate, … Read more
