Significance
A simple method for deprotection of tert-butyldimethylsilyl (TBDMS) ethers using silica-supported sodium hydrogen sulfate was developed. Thus, silica-supported sodium hydrogen sulfate (1) was prepared according to the reported procedures (G. W. Breton J. Org Chem. 1997, 62, 8952-8954). The TBDMS ethers 2, prepared from both primary and secondary alcohols, underwent deprotection with 1 in CH2Cl2 to give the corresponding alcohols 3a-m (13 examples, 89-94% yield).
