Application

N-(Phenylseleno)phthalimide is a versatile selenamide reagent and has been used:
  • to selectively derivatize thiols for mass spectrometric analysis
  • to derivatize thiol peptides in protein digests
  • in L-prolinamide or pyrrolidine trifluoromethanesulfonamide promoted α-selenenylation reactions of aldehydes and ketones
  • for introducing PhSe into protected glycals, ketones, aldehydes, stannanes and exocyclic alkenes

[reaction: see text] A new catalytic method for direct alpha-selenenylation reactions of aldehydes and ketones has been developed. The results of exploratory studies have demonstrated that L-prolinamide is an effective catalyst for alpha-selenenylation reactions of aldehydes, whereas pyrrolidine trifluoromethanesulfonamide efficiently
