On the Reaction of Oxalic Amidines with Carbonic Acid Derived Heterocumulenes to Imidazolidine-Derivatives

A useful synthetic route to nonsymmetric derivatives of imidazolidine (derivatives of parabanic acid) is demonstrated by the reaction of tetraarylated oxalic amidines 1 with different alkyl- and aryl substituted isothiocyanates 4, isoselenocyanates 31, and carbodiimides 30.Acylisothiocyanates 9 react differently leading to a mixture of three cycloacylation products 12, 13 and 14.Silylated heterocumulenes such as 25 and 26 react with 1 to give 28 and 29 transsilylation.Based on the 13C-n.m.r. spectroscopic investigation of the reaction between 1a and methyl isothiocyanate and phenyl isothiocyanate respectively a mechanism is proposed.
