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

A new route to chiral diol systems has been developed based on double nucleophilic addition to the cationic ions fixed on a 6-membered ring system using chiral hydrobenzoin as an auxiliary.
