Description
- Application: Pyridinium p-toluenesulfonate is a mild and efficient catalyst for the formation and cleavage of acetals.[1][2][3][4][5][6][7] This method has been adapted in the completely symmetric synthesis of tetrahydrolipstatin.[8] It is also capable of selectively cleaving tert-butyldimethylsilyl (TBDMS) ethers in the presence of tert-butyldiphenlysilyl (TBDPS) ethers.[9]
