A convienent one-pot synthesis of macrocycles containing a tetraaminoethene substructure is described. Starting from oxalic amidines 1, reduction with lithium and subsequent addition of phenyl isothiocyanate afforded the anionic bis(thiocarbamoyl) derivatives 3. In the final step, a ring-closure reaction using a large number of α,ω-dielectrophilic building blocks yields the new macrocyclic compounds 6-14.
