An efficient method for the asymmetricsynthesis of 4H-3,1-benzoxazines was developed by kinetic resolution of 2-amido benzyl alcohols using chiral phosphoric acidcatalyzed intramolecular cyclizations. A broad range of benzyl alcohols (both secondary and tertiaryalcohols) were kinetically resolved with high selectivities, with an s factor of up to 94. Mechanistic studies were performed to elucidate
