A convenient, efficient method for the preparation of benzoxazines is described. 2-(Hydroxyiminomethyl)benzyl alcohols were cyclodehydrated to construct 1H-2,3-benzoxazines by acid-catalyzed intramolecular Mitsunobu reaction. This reaction depended on the geometry of the hydroxyimino moiety in the r
