Summary: This study demonstrated the use of triazenyl alkynes as versatile building blocks in multicomponent reactions, leading to the synthesis of beta-amino amides with high diastereoselectivity and structural diversity. The bifunctionality of triazenyl alkynes, acting as both C2 fragment and directing group, played a crucial role in achieving the desired outcomes. Furthermore, the triazenyl group allowed for diverse late-stage transformations, opening up new possibilities for building block discovery and rational design of MCRs.

Summary: A general synthetic strategy is reported for producing various phenyl-group-terminated polyethenes and poly(alpha-olefins), which can be transformed into different telechelic polyolefins through postpolymerization reactions. These materials serve as building blocks for polyolefin-based synthetic polymers, as demonstrated by the syntheses of well-defined polyolefin-polyester di- and triblock copolymers.

Summary: Aldoses and ketoses can glycate proteins to form isomeric Amadori and Heyns products, with d-fructose being more involved in glycoxidation than d-glucose. Despite extensive studies on Amadori products and glucation, the in vivo effects of fructation remain largely unknown. The incorporation of a specific building block in solid-phase peptide synthesis allowed for the identification and characterization of glycated peptides.

Summary: A full atom-economical domino method has been developed for the preparation of alkyl 5-amino-4-cyano-1H-pyrrole-2-carboxylates by transannulation of 5-alkoxyisoxazoles with malononitrile under Fe(ii) catalysis. Alkyl 5-amino-4-cyano-1H-pyrrole-2-carboxylates are excellent building blocks for various annulation reactions, leading to new derivatives of 1H-pyrrolo[1,2-a]imidazole and pyrrolo[2,3-d]pyrimidine. The DFT calculations of mechanistic details of alkyl 5-amino-4-cyano-1H-pyrrole-2-carboxylate formation are presented.
