Abstract
Regioselective syntheses of cryptands were achieved via two different approaches, first by protection–deprotection and second by cyclization reactions between 1,ω-dihaloalkanes and the lariat amino triazolophanes. The syntheses of all triazolophanes and cryptands were carried out regioselectively, and the compounds were obtained in good yields. All compounds were studied and confirmed with different spectroscopic tools.
