Abstract

The substituted imidazolidines (2, 3, 5) and a ring-opening product, N,N,N’2-trisubstituted 2-methyl-ethylenediamines (4), derived from addition of the carbon anions to 1-tosyl-3,4-dimethylimidazolinium iodide (1), were utilized to transfer substituted one-carbon units to various amines to yield a series of functionalized β-enamino compounds.
