摘要: Abstract Stable α-methoxy arylmethyl carbanions can be generated by metalation of methyl ethers, 1 , with n -BuLi in THF at −40 °C, avoiding Wittig rearrangement to the corresponding alkoxides 2 . Reaction these various electrophiles afforded expected products 3 satisfactory yields. Connection between procedure and reductive electrophilic substitution ethers allowed transformation compounds into 2-arylpropanoic acids, 5
