The utility of diazinyl substituted carbodiimides ( 1a‐c ) for the synthesis of novel guanidines ( 2 ), isothioureas ( 3 ), and isoureas ( 4 ) is shown. Attempts to determine the stereochemistry of the target compounds using NOE difference spectroscopy or X‐ray analysis, respectively, are described.
