Asymmetric synthesis using C2-symmetric diols: Use of (5R,6R)-2,3-diacetoxy-5,6-diphenyl-1,4-dioxane as a chiral synthesis equivalent of 1,2-ethanediol 1,2-dicarbocation

A new route to chiral diol systems has been developed based on the double nucleophilic addition to (5R,6R)-2,3-diacetoxy-5,6-diphenyl-1,4-dioxanes using chiral hydrobenzoin as an auxiliary.
