摘要

The 4-hydroxyphenyl allyl ethers in refluxing aqueous methanol in the presence of KOH and oxygen furnish 2-substituted 1, 4-dihydroxybenzene derivatives; products and are derived base catalysed Claisen rearrangement, whereas presence of 3′-substitution on the allylic moiety disfavours this pathway, leading to fo
