Furthermore the present invention relates to vinylpyrimidine-2-one derivatives and of the general formula (Ia):
wherein R1 to R6 in formula (I) and in formula (Ia) represent independently of each other a variety of different substituents comprising alkyl, aryl, aralkyl, alkylaryl, heteroaryl groups and monofunctional moieties. The compounds are used as antivirals, especially against herpes and HCMV (Human Cytomegalovirus).

The stannylated pyrimidines form new carbon-carbon bonds by Pd(II)-catalyzed cross-couplings, tert-Butyldimethylsilyl-, dimethylthexylsilyl- and tert-butyldiphenylsilyl-oxymethyl (tri-n-butyl)tin have been synthesized and used in Pd(II)-catalyzed cross-couplingreactions with 4-chloropyrimidines. The silyi groups were not cleaved off during exposure to fluoride ions in aqueous media but were readily removed
