N-(1-alkenyl) derivatives of 2,4-pyrimidinediones (6-9) were prepared in a one pot synthesis from aldehydes and the nucleobases using trimethylsilyl trifluoromethanesulfonate (TfOTMS) as coupling reagent. Presilylation of the above nucleobases, and N6-benzoyladenine, with excess N,O-bis(trimethylsilyl)acetamide (BSA) followed by addition of one
