within a triplex currently remains elusive. A series of C1-ethenyl nucleosides have been devised and evaluated extensively for stability and specificity by molecular dynamics simulation. A synthesis via olefin metathesis of the unprotected heterocycle and a conveniently prepared anomerically pure C1-vinyl 2-deoxyribofuranose is presented as a significant improvement over a previously reported strategy.
