Application
It can be used:
- As a silylating agent for the synthesis of trimethylsilyl-enol ethers from esters of α-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.
