N-Pivot azacrown ethers (1, 2) and biscrown ethers (3, 4) were synthesized by Michael addition of monoazabenzo-15-C-5 with acrylic esters and amides. A simple and convenient method for preparing biscrown ethers in high yield was provided. All these compounds were indentified by IR, ^1H NMR, and MS.
