M. Scobie et al., LABELED COMPOUNDS OF INTEREST AS ANTITUMOR AGENTS .4. DEUTERATION ANDTRITIATION OF A NITROIMIDAZOLE-CARBORANE DESIGNED FOR BNCT, Journal of labelled compounds & radiopharmaceuticals, 34(9), 1994, pp. 881-885
Quenching the anion generated from a 2-(omega-carboranylalkyl)dithiane
with (H2O)-H-2 at -78 degrees C and at 0 degrees C introduced deuteri
um exclusively at C-2 of the carborane. Extension of this model reacti
on to a bioreductively-targetted carborane allowed the synthesis of 2-
[H-2]- and 2-[H-3]-isotopomers of a nitroimidazole-carborane which is
of interest in boron neutron capture therapy (BNCT) of cancer.
