Gold vs Light: Chemodivergent Reactivity of Diazoesters toward 2H‑Azirine-2-carboxylic Acids

An orthogonal reactivity of diazo compounds toward azirine-2-carboxylic acids, switching with the reaction conditions, is demonstrated. A gold-catalyzed reaction is N-selective and produces 1,3-oxazin-6-ones, whereas a blue light activation leads to O–H ...

1,4,2-Diazaborole-type heterocycle from 2H-azirine-2-carboxylate and [(alkylamino)methyl]trifluoroborate

text学術雑誌論文 / Journal ArticleA 1,4,2-diazaborole-type heterocycle was obtained via addition of [(alkylamino)methyl]-trifluoroborate to 2H-azirine-2-carboxylate. The molecular structure of the product was confirmed by X-ray crystallography.
