実験手順

Triiodomesitylene is converted under acetylating conditions in an oxidation reaction with potassium permanganate/acetic anhydride/acetic acid/sulfuric acid into triacetate (yield: 35%). The triacetate is isolated and saponified with potassium carbonate in methanol to tris alcohol (yield: 94%). The tris alcohol is then reacted to form tris aldehyde by Swern oxidation in dimethyl sulfoxide as a solvent in a yield of 67%.
