Description
Trimethylsilyl trifluoromethanesulfonate has been used in combination with boron trifluoride etherate for the copper-catalyzed asymmetric allylic alkylation (AAA) of allyl bromides, chlorides, and ethers with organolithium reagents in the presence of a chiral ligand.It can be used:As a silylating agent for the synthesis of trimethylsilyl-enol ethers from esters of +a-diazoacetoacetic acid.To activate benzyl and allyl ethers for the alkylation of sulfides.To facilitate the conversion of Diels-Alder adducts of Danishefsky's diene to cyclohexenones without the formation of methoxy ketone by-product.To prepare difluoroboron triflate etherate, a powerful Lewis acid especially in acetonitrile solvent. As a reagent in a Dieckmann-like cyclization of ester-imides and diesters.It may also be used to catalyze:Acylation of alcohols with acid anhydrides.Reductive coupling of carbonyl compounds with trialkylsilanes to form symmetrical ethers.Glycosidation of 4-demethoxydaunomycinones with 1-O-acyl-L-daunosamine derivatives.
