Cleavage or Acetyl-de-alkylation of 4-Methoxybenzyl (MPM) Ethers Using Acetic Acid
摘要:
Aryl (4-methoxyphenyl)methyl (MPM) ethers are cleaved by heating with acetic acid for a few hours at 90-degrees-C, producing the corresponding phenols and (4-methoxyphenyl)methyl acetate. Under the same conditions alkyl MPM ethers are transformed directly into the corresponding alkyl acetates.
Copper(II) bromide as efficient catalyst for silyl- to bisarylmethyl ethers interconversion (transprotection)
摘要:
Primary and secondary silylated alcohols are easily converted to bis(methoxyphenyl)methyl (BMPM) ethers in good yields using CuBr2 as catalyst in acetonitrile at room temperature. Various other protecting groups are compatible with this mild and convenient process. (C) 2011 Elsevier Ltd. All rights reserved.
