A variety of acetals and ketals are efficiently and rapidly converted to the corresponding carbonyl compounds by using WCl6 in dichloromethane or acetonitrile at room temperature.

Dirhodium caprolactamate [Rh-2(cap)(4)] is an effective catalyst for benzylic oxidation with tert-butyl hydroperoxide (TBHP) under mild conditions. Sodium bicarbonate is the optimal base additive for substrate conversion. Benzylic carbonyl compounds are readily obtained, and a formal synthesis of palmarumycin CP2 using this methodology is described.
