A stereoselective radical-mediated hydrogermylation of the protected 5-ethynyluracil nucleosides with trialkyl-, triaryl,- or tris(trimethylsilyl)germanes gave (Z)-5-(2-germylvinyl)uridine, 2′-deoxyuridine, or ara-uridine as major products. Reaction of the β-triphenylgermyl vinyl radical intermediate with oxygen and fragmentation of the resulting peroxyradical provided also 5-[2-(triphenylgermyl)acetyl]pyrimidine

(Z)-5-(2-Bromovinyl)uracil was obtained by photoisomerization of the E. isomer. Similarly, (E)-5-(2-bromovinyl)-2'-deoxyuridine gave the required Z isomer. (Z)-5-(2-Bromovinyl)-2'-deoxyuridine is much less active against herpes simplex virus type 1 (HSV-1) and somewhat less active against herpes simplex virus type 2 than is the E isomer. Both isomers show similar activity against vaccinia virus. Therefore
