摘要

A one-pot methodology has been developed for the direct synthesis of symmetrically and unsymmetrically N-substituted derivatives of 1, 4, 7-triazacyclononane. In the course of these studies the unexpected eight-membered cyclic aminal 7 has been isolated via an acid- catalysed rearrangement of enamine 5.
