A novel annulation reaction of two enamine molecules with iodine under basic conditions to form 4-functionalized imidazolium salts has been established. In this reaction, iodine acts as both an iodinating reagent and a Lewis acid catalyst. Features of this synthetic method include facilitative preparation of substrates, no use of transition metals, mild reaction conditions, simplicity of operation

The invention relates to novel dihydropyrimidin-2(lH)-ones and dihydropyrimidin- 2(lH)-thiones of formula (la). The invention also relates to the use of such compounds as medicaments, and in particular as inhibitors of sodium iodide symporter (NIS) and reducers of iodine transport and/or accumulation into NIS expressing cells. The invention also concerns a pharmaceutical composition comprising at least one compound of formula (la) as active principle.
alkylation of enolates and acetylides has been achieved through the use of a decarboxylative benzylation strategy. Previous research in this area is often limited by the need for extended conjugation in the electrophiles that are coupled. Herein, we report that the use of 1,1'-bis(diphenylphosphino)ferrocene (dppf) ligand allows the coupling of simple benzyl electrophiles with enolates, while the use
