Facile Deprotection of Trimethylsilyl Ethers With Modified Borohydride Agents; 1-Benzyl-4-AZA-1-Azoniabicyclo[2.2.2]Octane Tetrahydroborate (Baaotb)1Versus Tetrabutylammonium Tetrahydroborate(TBATB)
摘要:
Deprotection of structurally different trimethylsilyl ethers with the modified borohydride agents BAAOTB and TBATB to their corresponding alcohols in reflexing t-BuOH is described. Both BAAOTB and TBATB are efficient reagents for this purpose. BAAOTB seems to be more selective than TBATB.
