| titleOfInvention | Enhanced regio-selectivity in glycol acylation |
| abstract | Methods of acid-catalyzed acylation of isohexides have been described. The method involves the reaction of isohexide and excess carboxylic acid in the presence of a Lewis acid or Bronsted acid catalyst. One or more Lewis acids and / or Bronsted acids can achieve high conversion rates of isohexide to the corresponding mono and diesters with much higher regioselectivity of exo -OH than the endo -OH of isohexide in the product. have. Certain catalytic acid species include zirconium chloride (ZrCl 4 ) and phosphonic acid (H 3 PO 3 ), which exhibit ratios of exo : endo reactivity of about 5: 1 and 4: 1, respectively. |
