Abstract A new 2, 3-diaminoconduritol derivative with the conduritol F structure was prepared starting from cyclohexa-1, 4-diene. Initially, a lactam, prepared by the cycloaddition of chlorosulfonyl isocyanate (CSI) to cyclohexa-1, 4-diene, was converted into an amino acid. The conversion of the acid functionality into an isocyanate resulted in the formation of an imidazolidinone derivative, formed by an intramolecular cyclization. In the second part ...
