Recent Developments in the Biosynthesis of Aziridines
ChemBioChem, Volume 25, Issue 16, August 19, 2024.Aziridines are highly strained three‐membered rings comprised of two carbon atoms and one nitrogen atom. Natural products containing aziridines have been known for decades and used as drugs, but the biological origins of the aziridine ring were unknown until 2021.

Reactivity of beta-aroylacrylic acids with diazodiphenylmethane
, 1998 The rate constants for 10 trans-substituted beta-aroylacrylic acids in their reaction with diazodiphenylmethane (DDM) were determined in ethanol at 30 degrees C. The intention was to study the transmission of electronic effects of substituents on the phenyl nuclei to the carboxylic group reaction center, through the -C(=O)-CH=CH-group.
