Abstract

Abstract: Nitrogen-pivot lariat ethers of varying ring sizes can be prepared by cyclization of an amine or appropriately substituted diol. Twelve-membered-ring nitrogen-pivot lariat ethers were synthesized by one of two approaches. The method used by Calverley and Dale primarily for the synthesis of nonlariat azamacrocycles involves cyclo-bis-dialkylation of an amine with 1, l l-diiodo-3, 6, 9-trioxaundecane (method C). Several monoaza-12-crown-4 ...
