Alpha,omega-diamino aliphatic ethers react under ambient conditions with dimethyl alpha,omega-dicarboxylates, in methanol as a solvent, to give the cyclic diamides in good yields. Their subsequent reduction with a borhoydride-dimethyl sulphide complex affords the respective diazacoronands.

A general method for the synthesis of diazacoronands
α,ω-Diamino aliphatic ethers react under ambient conditions with dimethyl α,ω-dicarboxylates, in methanol as a solvent, to give the cyclic diamides in good yields, and their subsequent reduction with lithium aluminium hydride affords the respective diazacoronands.
