Recent Applications of Propylene Carbonate as a Solvent in Sustainable Organic Synthesis

open access: yesChemSusChem, Volume 19, Issue 17, 14 September 2026.
This review evaluates propylene carbonate (PC) as a non‐toxic green solvent in organic synthesis, highlighting its performance in key reactions including cross‐couplings, asymmetric hydrogenations, peptide synthesis and biocatalysis. Across these processes, PC delivers yields comparable to conventional and alternative green solvents.

Synthesis and 1,3-Dipolar Cycloaddition Reactions of Chiral Maleimides

open access: yesMolecules, 1997
New routes to the synthesis of various novel chiral maleimides are described. The oxabicyclic anhydride 2 readily available exo-Diels-Alder adduct of furan and maleic anhydride was used as a vehicle, which in turn reacted with hydrochlorides of amino ...

Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.

Phospha-Münchnones: Electronic Structures and 1,3-Dipolar Cycloadditions

open access: yes, 2016
The reaction of imines, acid chlorides, PR3, and base generates a new class of 1,3-dipoles: phospha-Münchnones. These 1,3-dipoles can undergo cycloadditions with alkynes followed by loss of phosphine oxides to form pyrroles.

Die Jekyll‐und‐Hyde‐Natur von Tetrazolen in der Polymerwissenschaft: Von der intrinsischen elektronischen Dualität zur programmierbaren makromolekularen Funktion

open access: yesAngewandte Chemie, Volume 138, Issue 36, 1 September 2026.
Ein Heterocyclus – drei elektronische Identitäten. Dieses Minireview zeigt, wie das Substitutionsmuster von Tetrazolen deren Funktion in Polymeren bestimmt und eröffnet substitutionsdefinierte Designprinzipien für funktionelle Polymermaterialien. ZUSAMMENFASSUNG Die Natur vereint Stabilität und Responsivität in einzelnen molekularen Gerüsten und ...

The Jekyll and Hyde Nature of Tetrazoles in Polymer Science: From Intrinsic Electronic Duality to Programmable Macromolecular Function

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 36, 1 September 2026.
Tetrazoles are reframed as substitution‐programmable heterocycles rather than static functional groups in polymer chemistry. By linking electronic identity to synthetic strategy and polymer architecture, this mini‐review establishes a design framework for translating tetrazole duality into predictable macromolecular function.
