INTRAMOLECULAR CYCLIZATION OF N,N-Di(OLIGOOXYETHYLENE)AMINES: A NEW SYNTHESIS OF MONOAZA CROWN ETHERS

Maeda, Hirokazu,Furuyoshi, Shigeo,Nakatsuji, Yohji,Okahara, Mitsuo

, p. 3359 - 3362 (1982)

The reaction of N,N-di(oligooxyethylene)amines with arenesulfonyl chloride in the presence of alkali metal hydroxide was investigated.It was found that the monoarenesulfonates of N,N-di(oligooxyethylene)amines were first formed as intermediates, and their subsequent intramolecular cyclization gave N-unsubstituted monoaza crown ethers rather selectively.
