Triacetoxyperiodinane → 2-(1,3-Dioxaindan-5-yl)acetaldehyde

Participants

Reaction Steps

A solution of 2-benzo[1,3]dioxol-5-yl-ethanol (Intermediate D2) (1 g; 6.0 mmol) in dichloromethane (40 mL) was treated with the Dess-Martin periodinane (commercially available from Lancaster) (2.65 g, 6.25 mmol) at rt for 2 h. Silica gel was added to the mixture and the solvent was removed under vacuum. The solids were placed onto a column of silica gel and the product was eluted with a mixture of ether:hexanes to give benzo[1,3]dioxol-5-yl-acetaldehyde (Intermediate D3) 0.75 g.
