Visible-light photoredox catalysis enables the synthesis of biologically relevant isoxazolines and isoxazoles from hydroxyimino acids. The process shows broad functional group compatibility and mechanisitic and computational studies support a visible-light-mediated...
1, 1'-Carbonyldiimidazole (1) is a useful reagent for the preparation of arylacetonitriles (9) from 3-aryl-2-hydroxyiminopropionic acids (8), and 2, 2'-oxalyldi (o-sulfobenzimide) (2) can also be used for this purpose under essentially neutral conditions.
