  Facile Cleavage of Triethylsilyl (TES) Ethers Using o-Iodoxybenzoic Acid (IBX) without Affecting tert-Butyldimethylsilyl (TBS) Ethers

  摘要：

  [GRAPHICS]In DMSO cleavage of triethylsilyl (TES) ethers by o-iodoxybenzoic acid (IBX) was significantly faster than cleavage of tart-butyldimethylsilyl (TBS) ethers or further oxidation into carbonyl compounds. In most cases, TES protecting groups could be removed in good to excellent yields within 1 h, whereas similar TBS protecting groups remained intact under the same conditions. The procedure also could be adapted for direct one-pot conversion of TES ethers into carbonyl compounds.

• Efficient chemoselective deprotection of silyl ethers using catalytic 1-chloroethyl chloroformate in methanol

  Fast and chemoselective desilylation of silyl-protected alcohols was achieved using a catalytic amount of 1-chloroethyl chloroformate in methanol. With a minimal amount of 1-chloroethyl chloroformate as the source for anhydrous HCl, extremely efficient cleavage of silyl ethers of primary and secondary alcohols was accomplished, and chemoselective deprotection of one silyl ether in the presence of another silyl or other acid-labile group was possible through controlling the amount of the chloroformate and reaction time.

  A very mild and environmentally benign method for ­removal of silyl protecting groups using catalytic amounts of iron ion in MeOH is presented. The method is particularly effective for cleaving triethylsilyl (TES) protecting groups.
