Tumour-targetted Boranes. Part 3. Synthesis of Carbamate-linked Nitroimidazolyl Carboranes Designed for Boron Neutron Capture Therapy of Cancer

Carboranes targetted to specific tumour tissues are important for boron neutron capture therapy of cancer (BNCT).Carbamoylation of 2-ethoxy>ethanol 5 and 1-(chloromethyl-2-(nitroimidazol-1-yl)ethanol 6 with carboran-1-yl isocyanate (generated in situ by a Curtius rearrangement of carborane-1-carbonyl azide) gave the corresponding carbamate-linked nitroimidazolylcarboranes 16 and 17.A similar reaction of 4-carboranylphenyl isocyanate with 6 afforded the corresponding carbamate 24.
