title: Synthesis of nucleoside 3',5'-cyclic boranophosphorothioate, a new type of cyclic nucleotide.
abstract: The first examples of a borane-containing doubly P-modified chiral cyclic nucleoside monophosphate (cNMP), e.g., thymidine and 5-fluoro-2'-deoxyuridine 3',5'-cyclic boranophosphorothioates, have been synthesized; these cNMP analogues with increased lipophilicity could be potential anticancer prodrugs and useful probes for mechanistic studies.
