temperature with DDQ in dichloromethane-water (9:1). The reaction conditions are compatible with the presence of other ethereal functionalities such as acetonides, allyl, benzyl, TBS, TBDPS groups. We have also shown that deprotection of prenyl ethersusing a catalyticamount of DDQ in the presence of 3 equivalents of Mn(OAc) 3 is a good alternative for the use of a stoichiometric amount of DDQ, albeit the
