Ring‐opening of <i>N</i>‐Tosyl Aziridines with Hydroxyl Compounds Catalyzed by Acidic Ionic Liquid

Abstract

Abstract Ring‐opening of two types of N ‐tosyl aziridines with hydroxyl compounds has been studied. The aziridines could react smoothly with alcohols in the presence of functional ionic liquid [hmim]HSO 4 to afford the corresponding β ‐amino ethers in moderate to good yields with high regioselectivity. The recyclable property of [hmim]HSO 4 was demonstrated in the process.
