Diverse reactivity of maleimides in polymer science and beyond. [PDF]
Polym IntThis mini‐review provides a thorough overview of maleimide chemistry, highlighting its diverse reactivity in polymer and materials science applications. Abstract Maleimides are remarkably versatile functional groups, capable of participating in homo‐ and copolymerizations, Diels–Alder and (photo)cycloadditions, Michael additions, and other reactions ...

Azirine ligation: fast and selective protein conjugation via photoinduced azirine–alkene cycloaddition [PDF]
Chemical Communications, 2010 We report a new bioorthogonal ligation reaction between p-nitrodiphenylazirine and dimethyl fumarate. This photoinduced azirine-alkene cycloaddition provides a rapid (~2 min) and highly selective route to protein conjugation at neutral pH and room temperature in biological medium.

Acremolin, a stable natural product with an antiaromatic 1H-azirine moiety? A structural reorientation [PDF]
, 2012 Recently, acremolin (4), a novel modified base, was isolated from a marine-derived fungus and claimed to possess a structure with a 1H-azirine moiety. It is shown now that the reported NMR data are not compatible with this antiaromatic heterocycle, which

[3 + 2]-Cycloadditions of nitrile ylides after photoactivation of vinyl azides under flow conditions
Beilstein Journal of Organic Chemistry, 2013 The photodenitrogenation of vinyl azides to 2H-azirines by using a photoflow reactor is reported and compared with thermal formation of 2H-azirines. Photochemically, the ring of the 2H-azirines was opened to yield the nitrile ylides, which underwent a [3
