Application

N-Phenylhydroxylamine can be used as a starting material for the synthesis of:
  • 2-alkylindoles by treating with aliphatic terminal alkynes using gold catalyst via sequential 3,3-rearrangements and cyclodehydrations.
  • Isoxazolidines by reacting with aldehydes and α, β-unsaturated aldehydes via a three-component one-pot catalytic reaction.
  • Tetrahydro-1,2-oxazines by treating with an aldehyde and cyclopropane via homo 3+2 dipolar cycloaddition reaction.

Previous studies have shown that incubation of rat red blood cells in vitro with phenylhydroxylamine (50-300 microM) induces rapid splenic sequestration of the red cells on reintroduction to isologous rats. EPR and the spin trapping agent, 5,5-dimethyl-1-pyrroline-N-oxide (DMPO), were utilized
