objectives
  • Dess-Martin periodinane (DMP) is a chemical
    reagent used to oxidize primary alcohols to
    aldehydes and secondary alcohols to ketones

4
background
  • This periodinane has several advantages over
    chromium- and DMSO-based oxidants that include
    milder conditions (room temperature, neutral pH),
    shorter reaction times, higher yields, simplified
    workups, high chemoselectivity, tolerance of
    sensitive functional groups, and a long shelf
    life. It is named after the American chemists
    Daniel Benjamin Dess and James Cullen Martin who
    developed the reagent in 1983. It is based on
    IBX, but due to the acetate groups attached to
    the central iodine atom, DMP is much more soluble
    in organic solvents

Application
  • In one application of the dess-martin oxidation,
    involves transforming a sensitive a-ß-unsaturated
    alcohol to its corresponding aldehdye.
  • This moiety has been found in several natural
    producs and due to its high functionality, it
    could be a valuable synthetic building block in
    organic synthesis.
  • Thongsornkleeb and Danheiser oxidized this
    sensitive alcohol by employing the Dess Martin
    Oxidation and altering the work up procedure
    (diluting with pentanes, washing with
    poly(4-vinylpyridine) to remove the acetic acid
    generated during the reaction, filtering and
    concentrating via distillation.14
