Abstract
Reactions of optically pure 1-aryl-2,2-dimethylpropane-1,3-diols with phenylglyoxal give diastereomerically pure cyclic ketals under acid ca talyzed conditions. The structure of one of the products, orophenyl)-5 ,5-dimethyl-1,3-dioxane-2-carbaldehyde (7), has been determined by X-r ay crystallography; reaction takes place at the keto group and the ald ehyde group is oriented axially.
