ambident 3-hydroxyisoxazoles, which are heterocyclic bioisosteres of carboxylic acids, predominates underMitsunobuconditions. In several cases, excellent O-regioselectivity (⩾95%) was observed. It is noteworthy that reactions were complete within 15 min at room temperature. Furthermore, the conditions are compatible with a range of alcohols that cover all of the typical protecting groups for the 3-hydroxyisoxazole
