Abstract : A process for preparing 3-hydroxyoxetane comprising the following steps is disclosed: (1) reacting a carboxylic acid of the formula CH3(CH2)nCOOH with epichlorohydrin in the presence of anhydrous ferric chloride to produce an ester; (2) protecting the secondary hydroxy group of the ester with a blocking group, z, that is stable oto bases; thus forming a blocked ester; (3) hydrolyzing the blocked ester formed in step (2) with an aqueous base to remove the carboxylic acid and form a 3-hydroxyoxetane derivative; (4) removing the blocking group from the 3-hydroxyoxetane derivative by heating it with an alcohol and an acid to form the product 3-hydroxyoxetane.
