A General Regioselective Synthesis of 2,4-Diarylpyrimidines from 2- Thiouracil through Two Orthogonal Cross-Coupling Reactions

Abstract

A novel efficient synthesis of 2,4-diarylpyrimidines was developed based on phosphonium-mediated Suzuki coupling of 2-(methylsulfanyl)pyrimidin-4(3H)-one (at position 4) followed by the Liebeskind–Srogl cross-coupling (at position 2) under microwave irradiation.

Key words

pyrimidines - uracil - cross-coupling - arylation - microwave - palladium
