Mild deprotection of tert-butyl and tert-amyl ethers leading either to alcohols or to trialkylsilyl ethers
摘要:
Tert-butyl and tert-amyl ethers afford the corresponding tert-butyldimethylsilyl ethers when treated by one equivalent of tert-butyldimethylsilyl triflate (TBDMSOTf), followed by one equivalent of 2,6-lutidine. However, treatment by a catalytic amount of TBDMSOTf without base, led to the corresponding free alcohols.
