Triacetoxyperiodinane → 8-(Tert-butyl-dimethyl-silanyloxymethyl)-naphthalene-1-carbaldehyde

Participants

Reaction Steps

[8-(tert-Butyl-dimethyl-silanyloxymethyl)-naphthalen-1-yl]-methanol (Aust. J. Chem. 1996, 49, 793-800) (0.2 g, 0.66 mmol) was dissolved in dichloromethane (8 mL). To the solution was then added 1,1,1-triacetoxy-1,1-dihydro-1,2-benziodoxol-3(1H)-one, also known as Dess-Martin periodinane (0.56 g, 1.32 mmol). The reaction mixture was stirred for 1 hr then partitioned with an aqueous saturated solution of thiosulfate and dichloromethane. The organic layer was washed with an aqueous saturated solution of thiosulfate, an aqueous saturated solution of sodium bicarbonate, brine, dried with Na2SO4, filtered and the solvent evaporated in vacuo to yield a crude oil. The crude oil was purified via flash chromatography (6.0% ammonia 2.0 M in methanol/dichloromethane) to yield 8-(tert-butyl-dimethyl-silanyloxymethyl)-naphthalene-1-carbaldehyde as a clear oil.
