An extremely practical synthesis of 4,10-diaza-15-crown-5, 4,13-diaza-18-crown-6, and symmetrically N,N′-disubstituted derivatives thereof, is presented along with the first survey of cationbinding data for the 15-membered ring systems.

The syntheses of novel cage-annulated diaza (17-crown-5) lariatcrownethers, i.e.,10–16 are reported. A series of alkali metal picrate extraction experiments have been performed by using this new class of synthetic ionophores in order to evaluate the effects of cage-annulation and the influence ofN-pivotside-arms upon complexationproperties. The results thereby obtained indicate that complexation

Solution thermodynamic data and solidstatestructure information are used to show that a series of ,'-(substituted)-4,13-diaza-18-crown-6 (BiBLE) derivatives which lack oxygen or nitrogen donor groups in the sidearms do not utilize the sidearms for binding but show considerable variation in their binding constants.
