We have developed an efficient and extensive deuterium incorporation method using a heterogeneous Pd/C-D2O-H2 system into the base moiety of nucleosides. The results presented here provide a deuterium gas-free, totally catalytic, and post-synthetic deuterium labeling method in D 2O media. Georg Thieme Verlag Stuttgart.

METHOD FOR DEUTERATION OR TRITIATION OF HETEROCYCLIC RING

Page/Page column 16, (2008/06/13)
The present invention relates to a method for deuteration of a heterocyclic ring, which comprises subjecting a compound having a heterocyclic ring to sealed refluxing state in a deuterated solvent in the presence of an activated catalyst selected form a palladium catalyst, a platinum catalyst, a rhodium catalyst, a ruthenium catalyst, a nickel catalyst and a cobalt catalyst. In accordance with a method of the present invention, a hydrogen atom belonging to a heterocyclic ring of a compound having a heterocyclic ring can be very efficiently deuterated because temperature of deuteration reaction can be maintained at higher than boiling point of the solvent. Further, a method for deuteration of the present invention can be applied widely to deuteration of various compounds having a heterocyclic ring which are liable to decomposition under supercritical conditions or acidic conditions, leading to industrial and efficient deuteration of a compound having a heterocyclic ring.

, p. 361 - 369 (2007/10/03)
The D2 gas-free and base-selective H-D exchange reaction of nucleosides was developed. It discloses a convenient route to the post-synthetic incorporation of deuteriums into the base moiety of nucleic acids with high deuterium efficiency.
