Synthese und polymerisation eines vinylmonomeren der nucleobase thymin

Chemistry of some-5-(2-hydroxyalkyl)uracil derivatives and a synthesis of 5-vinyluracil

“…The mechanism and the scope of this reaction will be the subject of a future report. The propenoic acid derivative 13 was synthesized by the condensation of 5-formyluracil (12)56 with malonic acid, to give exclusively the trans isomer as evidenced by nmr data.…”
