Ring-opening of N-Tosyl Aziridines with Hydroxyl Compounds Catalyzed by Acidic Ionic Liquid

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]HSO4 to afford the corresponding β‐amino ethers in moderate to good yields with high regioselectivity. The recyclable property of [hmim]HSO4 was demonstrated in the process. Ring‐opening of two types of N‐tosyl aziridines with hydroxyl compounds has been studied.
