Reagents for new heteroannelation reactions. Part I: Isocyanate-dithioketal reagents

Extending our earlier work on hetero-annelations some isocyanate-dithioketals were reacted with various educts: while heteroaromatic 2-aminoesters gave cyclization to a pyrimido moiety, the corresponding 2-aminonitriles led in one-pot reactions to double-annelation, yielding products containing an imidazopyrimido moiety.
