Metal–organic framework of NH2-MIL-53(Al), with coordinative unsaturated aluminium sites, has been shown to 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.

Abstract: In this work, magnetic spent coffee ground as a green, inexpensive, and abundant material was synthesized and characterized by a variety of techniques, including X-ray diffraction pattern, thermal gravimetric analysis, scanning electron microscopy, energy-dispersive spectroscopy, inductively coupled plasma optical emission spectrometry, and Fourier transform infrared spectroscopy. The magnetic spent coffee ground was successfully utilized as a catalyst in aerobic oxidation of primary and secondary benzylic alcohols and tandem oxidative Groebke–Blackburn–Bienaymé reaction.

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-Bienaymé 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. Georg Thieme Verlag Stuttgart - New York.

Superparamagnetic nanoparticles of modified sulfuric acid (γ-Fe2O3@SiO2-OSO3H) represent a straightforward and green catalyst for the rapid synthesis of aminoimidazopyridine skeletons via the Ugi-like Groebke-Blackburn-Bienaymé three-component reaction. The γ-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.
