One way to increase the number of points of diversity is by combining a reaction with 2-Methyleneaziridine with the Bucherer—Bergs reaction in a one-pot synthesis see Buchereg 1. The Bucherer—Bergs reaction is the chemical reaction of carbonyl compounds aldehydes or ketones or cyanohydrins with ammonium carbonate and potassium cyanide to give hydantoins.

Journal of the Chemical Society Resumed. A variety of alkylating and acylating agents including benzylic, allylic halides can be used in this reaction, in a reaction much similar to the enamine alkylation, enamines can be acylated to form a final dicarbonyl product.

Bucherer reaction topic The Bucherer reaction in organic chemistry is the reversible conversion of a naphthol to a naphthylamine in the presence of ammonia and sodium bisulfite. Introduction Although Isaac Newton based his physics on absolute time and space, he also adhered to the principle of relativity of Galileo Galilei restating it precisely for mechanical systems [1].

Examples of such procedures are described for benzaldehyde, 2-tetralone, citral, the other main use of sodium bisulfite is as a mild reducing agent in organic synthesis in particular in purification procedures.

budherer This compound is deprotonated to the imine 5b or the enamine 5c but an equilibrium exists between both species. In Bucherer and Steiner proposed a mechanism for the reaction. Member feedback about 2-Naphthylamine: An imine is reduced in reductive amination, an imine reacts with an amine to an aminal, see for example the synthesis of cucurbituril.
