Photooxygenation of aziridines and some potential azomethine ylides

The Journal of Organic Chemistry, 1979
Sensitized photooxygenations of a few bicyclic aziridines and some potential azomethine ylides have been investigated. The photooxygenation of 1-cyclohexyl-6-(cyclohexylimino)-1a-phenylindano(1,2-b)aziridine (7) gave a 51% yield of 2-cyclohexyl-3-hydroxy-3-phenylphthalimidine (12). The photooxygenation of endo-2,4,6-triphenyl-1,3-diazabicyclo(3.1.0)hex-

Enal-azomethine ylides: application in the synthesis of functionalized pyrroles

Organic & Biomolecular Chemistry
Novel enal-azomethine ylides derived from diazoenals and N-alkyl imines gave N-alkyl-3-formyl pyrroles. The new methodology was used in the short synthesis of biologically relevant pyrrolo[3,2-c]quinoline and pyrrolo[2,1-a]isoquinoline scaffolds.

Development of amine functionalizations involving azomethine ylides

2015
Functionalization of amines is a very important research area in organic chemistry because functionalized amines are important building blocks in many biologically active compounds and pharmaceuticals. Outlined within this dissertation are our efforts toward the development of redox-neutral amine functionalizations involving azomethine ylides.
