The Groebke–Blackburn–Bienaymé (GBB) three-component reaction, discovered in 1998, is a very efficient strategy to assemble imidazo[1,2- ]-heterocycles starting from amidines, aldehydes and isocyanides. This review aims exhaustively describe innovative aspects of this reaction achieved during the last five years, classifies them into categories: synthetic methods, building blocks, scaffolds, biological activities physical properties.

The exploration of macrocycles began in the 20th century, coinciding with progressive advancement synthetic chemistry methodologies. From numerous strategies, Ugi reaction stands out as an efficacious four-component (4-CR). is particularly distinguished by its robust functional group tolerance, enabling creation that are both diverse and complex a singular step. This review collates contemporary examples macrocycles, all which have been crafted using to construct these macrocyclic frameworks. employment various bifunctional reagents (with same or different groups), has introduced plethora cyclization tactics, resulting synthesis multitude cage molecules. In order offer invaluable insights into construction use distinct colors for reactants made entire process transparently visible, thereby enhancing readers' understanding sparking their interest.

Utilizing CO2 as a one-carbon building block in the preparation of high-value chemical entities is cornerstone modern organic synthesis. Herein, we exemplify this strategy through mild, one-pot methodology that gives rapid access to N-heteroaryl substituted 6-, 8- and 9-membered carbamates via fixation.

Octafluorocyclopentene (OFCP) has found utility as a polyelectrophile in substitution cascades that form complex macrocyclic compounds. The Harran group synthesis of polypeptides depends on OFCP linker, combining with four different nucleophilic units polypeptide. We report computational investigation the origins reactivity and rationale for controlled mono-, di-, tri-, tetrasubstitution fluoride ions by heteroatomic nucleophiles. roles inductive, negative hyperconjugative, resonance electron-donation substituents are explored reaction OFCP, less-fluorinated analogues, common electrophilic alkenes several

Abstract Cyclic N ‐sulfonyl ketimines constitute an accessible class of lead‐like heterocycles with a vast application in both synthetic organic and medicinal chemistry. In this context, we harness the capabilities these four different isocyanide‐based multicomponent reactions. Our goal was to create libraries compounds functional groups vectors that are compatible for structural elaboration optimization their physical properties. We synthesized 15 unprecedented high diversity complexity, whereas have obtained single crystal structures each scaffold, unraveling geometrical features potential employment drug discovery.
