  2. Cyclohexylamine - Wikipedia

    en.wikipedia.org/wiki/Cyclohexylamine

    Cyclohexylamine is used as an intermediate in synthesis of other organic compounds. It is the precursor to sulfenamide -based reagents used as accelerators for vulcanization. The amine itself is an effective corrosion inhibitor. It has been used as a flushing aid in the printing ink industry. [5]

  3. Ei mechanism - Wikipedia

    en.wikipedia.org/wiki/Ei_mechanism

    mechanism. In organic chemistry, the Ei mechanism ( Elimination Internal/Intramolecular ), also known as a thermal syn elimination or a pericyclic syn elimination, is a special type of elimination reaction in which two vicinal (adjacent) substituents on an alkane framework leave simultaneously via a cyclic transition state to form an alkene in ...

  4. Strecker amino acid synthesis - Wikipedia

    en.wikipedia.org/wiki/Strecker_amino_acid_synthesis

    RXNO:0000207. The Strecker amino acid synthesis, also known simply as the Strecker synthesis, is a method for the synthesis of amino acids by the reaction of an aldehyde with cyanide in the presence of ammonia. The condensation reaction yields an α-aminonitrile, which is subsequently hydrolyzed to give the desired amino acid.

  5. Arndt–Eistert reaction - Wikipedia

    en.wikipedia.org/wiki/Arndt–Eistert_reaction

    In organic chemistry, the Arndt–Eistert reaction is the conversion of a carboxylic acid to its homologue. Named for the German chemists Fritz Arndt (1885–1969) and Bernd Eistert (1902–1978), the method entails treating an acid chlorides with diazomethane. It is a popular method of producing β-amino acids from α-amino acids.

  6. Paal–Knorr synthesis - Wikipedia

    en.wikipedia.org/wiki/Paal–Knorr_synthesis

    In organic chemistry, the Paal–Knorr synthesis is a reaction used to synthesize substituted furans, pyrroles, or thiophenes from 1,4-diketones. It is a synthetically valuable method for obtaining substituted furans and pyrroles, which are common structural components of many natural products. It was initially reported independently by German ...

  7. Cascade reaction - Wikipedia

    en.wikipedia.org/wiki/Cascade_reaction

    Cascade reaction. Cascade reactions are often key steps in the efficient total synthesis of complex natural products. The key step in Heathcock 's synthesis of dihydroprotodaphniphylline features a highly efficient cascade involving two aldehyde/amine condensations, a Prins-like cyclization, and a 1,5-hydride transfer to afford a pentacyclic ...

  8. Enantioselective synthesis - Wikipedia

    en.wikipedia.org/wiki/Enantioselective_synthesis

    Enantioselective synthesis, also called asymmetric synthesis, [1] is a form of chemical synthesis. It is defined by IUPAC as "a chemical reaction (or reaction sequence) in which one or more new elements of chirality are formed in a substrate molecule and which produces the stereoisomeric ( enantiomeric or diastereomeric) products in unequal ...

  9. Johnson–Corey–Chaykovsky reaction - Wikipedia

    en.wikipedia.org/wiki/Johnson–Corey...

    The Johnson–Corey–Chaykovsky reaction (sometimes referred to as the Corey–Chaykovsky reaction or CCR) is a chemical reaction used in organic chemistry for the synthesis of epoxides, aziridines, and cyclopropanes. It was discovered in 1961 by A. William Johnson and developed significantly by E. J. Corey and Michael Chaykovsky.
