  RuCl3 catalyzes the efficient Ugi-type Groebke–Blackburn condensations of aldehydes and 2-amino pyridines with isocyanides under solvent free conditions without any ligand or activator. It is shown that RuCl3 catalyzed aminoimidazole derivatives can be efficiently prepared under mild conditions and high tolerance with typical yields around 94%.

  be active in the Groebke–Blackburn–Bienaymé multicomponent coupling reaction based on Ugi‐type amine and aldehyde condensation over isocyanide and then a cyclization process. Interestingly this reaction occurred under solvent‐free conditions with high yield, in which the NH2‐MIL‐53(Al) could be recovered and reused for five reaction cycles, giving a total turnover number of 455.

• Three Novel Sequential Reactions for the Facile Synthesis of a Library of Bisheterocycles Possessing the 3-Aminoimidazo[1,2-a]pyridine Core Cata­lyzed by Bismuth(III) Chloride

  日期：——

  Novel, one-pot, two-step, sequential protocols for the synthesis of 1,4-phenylene bisheterocyclic compounds have been developed. Successive sequencing of the Groebke-Blackburn-Bienayme reaction with Ugi-azide, Hantzsch and Biginelli reactions results in rapid and efficient formation of bisheterocyclic compounds. A simple, fast and high yielding method for the synthesis of 3-aminoimidazo[1,2-a]pyridines catalyzed by bismuth(III) chloride under solvent-free conditions is reported. Bismuth(III) chloride is also an efficient catalyst for the Ugi-azide reaction under solvent free conditions.

  Superparamagnetic nanoparticles of modified sulfuric acid (gamma-Fe2O3@SiO2-OSO3H) represent a straight-forward and green catalyst for the rapid synthesis of aminoimidazopyridine skeletons via the Ugi-like Groebke-Blackburn-Bienayme three-component reaction. The gamma-Fe2O3@SiO2-OSO3H catalyst could be recovered and reused in five reaction cycles, giving a total TON = 453. The products were prepared under solvent-free conditions without any additives.
