Abstract: Medium-sized N-heterocycles, in particular eight-membered azocines, are key structures occurring in many natural products and in some compounds having biological activities. We described here an easy access to benzo[f][1,4]oxazocin-1-ones starting from 2-acetylbenzoic acid.
Keywords: eight-membered N, O heterocycles, ethanolamines, ZnCl<sub>2</sub>
