Descripción

Application

Pyridinium p-toluenesulfonate is a mild and efficient catalyst for the formation and cleavage of acetals. This method has been adapted in the completely symmetric synthesis of tetrahydrolipstatin. It is also capable of selectively cleaving tert-butyldimethylsilyl (TBDMS) ethers in the presence of tert-butyldiphenlysilyl (TBDPS) ethers.
