Abstract

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.
