ChemFiles Vol. 1, No. 2 • 2001Dess–Martin Periodinane

is widely used for the mild

oxidation of alcohols to

aldehydes and ketones.1

This reagent is especially useful

for substrates containing sensitive

functional groups and offers an

alternative to other mild

reagents (e.g. TPAP). Other

advantages such as selectivity,

rapid rates, avoiding the use of

toxic (i.e. chromium-based)

chemicals, using stoichiometric

amounts of reagent, and ease of

work up make the Dess–Martin

periodinane a reliable and easy-to-

use oxidizer in organic synthesis.

Dess–Martin PeriodinaneDess–Martin Periodinane

1. Useful in the preparation of epimerization-sensitive optically active N-protected α-amino aldehydes with high enantiomeric excess.2

2. Oximes and tosylhydrazones are converted to their corresponding carbonyl compounds under mild conditionswithout overoxidation of the final product.3

3. Oxidation of sugar hydroxyls in good yields with periodinane avoids the use of ruthenium dioxide.4

4. A highly unstable dialdehyde was prepared by oxidation with periodinane and trapped in situ with a pre-formed Wittig ylide.5

5. A convenient route to the preparation of highly reactive acyl nitroso compounds. These products can be trapped by dienes to form cycloadducts.6

6. Rapid production of complex and diverse natural product-like polycycles. A proposed mechanism starts with an ortho-oxidation followed by an intramolecular hetero Diels–Alder reaction.7

7. Neutral and mild work-up conditions avoid the formation of dehydrofluorinated by-products in the oxidation of polyfluorinated primary alcohols to aldehydes.8

Preparation of ArylaldehydesPreparation of ArylaldehydesVarious routes are available for the formation of arylaldehydes, including classical aromatic formylation viaVilsmeier, Gatterman, or Reimer–Tiemann reactions. Other methods include reduction of carboxylic acid derivatives,especially the reduction of esters with DIBAH9, and the oxidation of alcohols, typically with chromium reagents but accomplished under mild conditions with TPAP10 or Dess-Martin periodinane (see above).
