ABSTRACT:
A practical, selective process for preparing oxetanes is disclosed. A 1,3-glycol monosulfate salt is prepared by sulfation and neutralization of the corresponding 1,3-glycol. The neutral monosulfate salt is then reacted with a strong base, resulting in efficient ring closure to the oxetane.
