An efficient solid-phase synthesis of biologically important DNA-interactive pyrrolo[2,1-c][1,4]benzodiazepine dimers (DSB-120) and their C2-fluorinated analogues

A facile method for the solid-phase synthesis of pyrrolo[2,1-c][1,4]benzodiazepine dimers has been developed. p-Nitrophenyl carbonate Wang resin attached to 2-amino-5-methoxy-methyl benzoate has been utilized as the resin-bound starting material and these reactions are monitored by FT-IR spectroscopy of resin beads.
