21. Aldehydes and Ketones: Nucleophilic Addition / Imine vs Enamine / Problem 6
Acetals are used as protecting groups for 1,2-diols and carbonyl compounds (aldehydes and ketones). Formation of an acetal using a diol as an alcohol yields a cyclic acetal. Provide the cyclic acetal formed when the following compound reacts with cyclobutane-1,2-diol under acid catalysis.
