  2. Myers deoxygenation - Wikipedia

    en.wikipedia.org/wiki/Myers_deoxygenation

    In organic chemistry, the Myers deoxygenation reaction is an organic redox reaction that reduces an alcohol into an alkyl position by way of an arenesulfonyl hydrazine as a key intermediate. This name reaction is one of four discovered by Andrew Myers that are named after him; this reaction and the Myers allene synthesis reaction involve the ...

  3. Myers allene synthesis - Wikipedia

    en.wikipedia.org/wiki/Myers_allene_synthesis

    In organic chemistry, the Myers allene synthesis is a chemical reaction that converts a propargyl alcohol into an allene by way of an arenesulfonyl hydrazine as a key intermediate. [1] This name reaction is one of two discovered by Andrew Myers that are named after him; both this reaction and the Myers deoxygenation reaction involve the same ...

  4. Chiral auxiliary - Wikipedia

    en.wikipedia.org/wiki/Chiral_auxiliary

    Chiral auxiliaries are incorporated into synthetic routes to control the absolute configuration of stereogenic centers. David A. Evans' synthesis of the macrolide cytovaricin, considered a classic, utilizes oxazolidinone chiral auxiliaries for one asymmetric alkylation reaction and four asymmetric aldol reactions, setting the absolute stereochemistry of nine stereocenters.

  5. Reductive elimination - Wikipedia

    en.wikipedia.org/wiki/Reductive_elimination

    Reductive elimination is an elementary step in organometallic chemistry in which the oxidation state of the metal center decreases while forming a new covalent bond between two ligands. It is the microscopic reverse of oxidative addition, and is often the product-forming step in many catalytic processes. Since oxidative addition and reductive ...
