Description

Application

(R)-(-)-2,2-Dimethyl-1,3-dioxolane-4-methanol may be used to prepare:
• (R)-2,2-dimethyl-4-benzoxymethyl-1,3-dioxolane
• ((S)-(2,2-dimethyl-1,3-dioxolan-4-yl)methyl 4-methylbenzenesulfonate)-1,3-dioxolane
• (S)-glyceraldehyde acetonide

Both (R)- and (S)-forms are chiral synthons used in the preparation of tetraoxaspiroundecanes, diglycerides, and glyceryl phosphates.
