Highly Regioselective Addition of Organozinc Reagents to 2-Oxo-1,2-dihydropyrimidine-5-carboxylates Activated by BF<sub>3</sub>·OEt<sub>2</sub>: Synthesis of 2-Oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylates

The incorporation of alkyl as well as phenyl groups at C-4, a key position of 2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylates, responsible for antagonist/agonist switching of the calcium channel blocking activity of these compounds, has been achieved by the addition of organozincreagents to the corresponding 2-oxo-1,2-dihydropyrimidine-5-carboxylate derivatives catalysed by BF3OEt2.
