General description

Silver trifluoromethanesulfonate p-complexes of monoenes, dienes, trienes, monoynes and diynes have been prepared. It reacts with 2-fluoro- and 3-fluoro-4-alkoxystilbazoles to afford the mesomorphic complexes. Iodine monochloride/AgOTf constitutes an efficient promoter system for the O-glycoside synthesis.

Application

Silver trifluoromethanesulfonate (AgOTf) may be employed as a reagent during glucosylation of several alcohols. AgOTf in combination with p-nitrobenzenesulfenyl chloride may be employed as an activator for the glycosylation.
It may be used for the synthesis of the following:
  • cystine-containing peptides
  • 3-aminoalkylated indoles
  • benzo[b]oxepines and 2H-chromenes
  • diversely substituted iminoimidazoazines

Other Notes

Reagent for the substitution of halides by triflate.; Reagent for the glycosylation of glycosyl halides; Reagent used for the deprotection of protected thiols
