Synthesis of Nucleoside α-Thiotriphosphates via an Oxathiaphospholane Approach†
摘要:
Nucleoside 5 '-O-(alpha-thiotriphosphates) were obtained in reactions of the appropriate nucleoside 5 '-O-(2-thio-1,3,2-oxathiaphospholanes) with pyrophosphate in the presence of DBU. The presented method allows also for preparation of alpha-seleno congeners and corresponding a-modified diphosphates.
