✦ Synopsis

Nucleophilic ring opening of isopropylidene ketals by trimethylaluminum is described. This reagent offers a new method for selective monoprotection of 12-diols. The regioselectivity of this reaction was studied with simple diols and with carbohydrates.

Selective protection of a specific hydroxy group in a polyol is an important tool in organic synthesis I.
