An Efficient Method for Selective Deprotection of Trimethylsilyl Ethers and Tetrahydropyranyl Ethers under Solvent-free Conditions

摘要

l-Butyl-4-aza-l-azoniabicyclo[2.2.2]octane dichromate (BAABOD) 3 is a useful reagent for the selective cleavage of trimethylsilyl ethers and tetrahydropyranyl ethers to their corresponding aldehydes and ketones in the presence of AlCl_3 under solvent-free conditions.This method is very simple and efficient and the reaction has been carried out under solvent-free conditions in the presence of a catalytically amount of aluminum chloride.
