Yu, Haihua published the artcileControllable access to multi-substituted imidazoles via palladium(II)-catalyzed C-C coupling and C-N condensation cascade reactions, Formula: C9H12BClO3, the publication is Chemical Communications (Cambridge, United Kingdom) (2017), 53(70), 9745-9748, database is CAplus and MEDLINE.

A novel and efficient protocol for the synthesis of various 2,4-disubstituted, 1,2,4-trisubstituted and 1,2,4,5-tetra-substituted imidazoles I [R¹ = Me, CF₃, Ph, etc.; R² = H, Ph, Bn; R³ = H, Me; R⁴ = Ph, 4-FC₆H₄, 2-MeC₆H₄, etc.] via cascade palladium catalyzed C-C coupling followed by intramol. C-N bond formation was developed. Readily accessible boronic acids and N-substituted-2-aminoacetonitriles were firstly reported as starting materials to construct di-, tri-, and tetra-substituted imidazoles in good to excellent yield. The protocol was the first report to prepare multi-substituted imidazoles from readily accessible aminoacetonitrile and boronic acid.
