- 中文摘要: A short, efficient synthesis of 2-methoxy-6-alkyl-1,4-benzoquinones is described. Ultrasound-assisted Wittig reaction of alkyltriphenyl phosphonium bromides with o-vanillin in basic aqueous conditions followed by reduction with Na/n-BuOH gave 2-methoxy-6-alkylphenols. Oxidation of 2-methoxy-6-alkylphenols with Fremy’s salt produced the title compounds.
