Can be used, in the presence of an acid catalyst, for the introduction of the methoxyisopropyl protecting group for alcohols, readily removed under mild acid conditions. Unlike dihydropyran, the resulting acetals do not contain additional chiral centers (i.e. only a single diastereomer results): J. Am. Chem. Soc., 89, 3366 (1967); 94, 7827 (1972); 100, 4616 (1978).

Diols have been protected as their acetonides in the presence of dry HBr in dichloromethane: J. Am. Chem. Soc., 100, 4620 (1978), or TsOH in DMF: J. Chem. Soc., Chem. Commun., 21 (1980), used for selective protection of a 1,3- rather than a 1,2-diol in a sugar.
