Three novel calix[4](aza)crown deravatives have been synthesized,including a new [2]pseudorotaxane in which calix[4]- azacrown behaves as a stopper,a novel‘tren’type calix[4]azacrown and a novel‘spiro’type calix[4]azacrown containing morpholine unit.The structures of these compounds have been confirmed by NMR and MS.
