Bi(III) SALTS AS NEW CATALYSTS FOR THE SELECTIVE CONVERSION OF TRIMETHYLSILYL AND TETRAHYDROPYRANYL ETHERS TO THEIR CORRESPONDING ACETATES AND FORMATES

Bi(III) salts such as BiCl 3 , Bi(TFA) 3 and Bi(OTf) 3 were found to be efficient catalysts for the transformation of trimethylsilyl (TMS) and tetrahydropyranyl (THP) ethers to their corresponding acetates and formates with acetic acid and ethyl formate. Selective acetylation and formylation of TMS...

Description
Summary:Bi(III) salts such as BiCl 3 , Bi(TFA) 3 and Bi(OTf) 3 were found to be efficient catalysts for the transformation of trimethylsilyl (TMS) and tetrahydropyranyl (THP) ethers to their corresponding acetates and formates with acetic acid and ethyl formate. Selective acetylation and formylation of TMS and THP ethers of alcohols in the presence of phenolic TMS and THP ethers make this method a useful and practical procedure in organic synthesis.
