title: Synthesis, characterization, and binding property of isoelectronic analogues of nucleobases, B(6)-substituted 5-aza-6-borauracils and -thymines.
abstract: As isoelectronic BN-containing analogues of 6-substituted uracil and thymine, a series of B(6)-substituted 5-aza-6-borauracils (U(BN)s) and -thymines (T(BN)s) were synthesized and fully characterized. The crystallographic and spectroscopic analyses of the analogues revealed that the framework and hydrogen-bonding pattern of T(BN)s were similar to those of the original nucleobase, thymine.
