Received Date: 12 July 1995

Fund Project: Project supported by National Natural Science Foundation of China.

Azacrown ethers with intraannular phenolic groups are readily prepared by the reaction of 1,8-bis(p-tolylsulphonylamino)-3,6-dioxaoctane with 2,6-bis(bromomethyl)-4-R-anisole (R=CH₃,Cl,Br) in a two-phase system of aqueous lithium hydroxide-toluene in the presence of Bu₄ NI as phase transfer catalyst.
