One-Pot Synthesis of 3-Methylflavones and Their Transformation into (E)-3-Styrylflavones via Wittig Reactions
摘要:
An efficient one-pot synthesis of 3-methylflavone derivatives is established. Furthermore, their transformation into phosphorus ylides, which are then used in the diastereoselective synthesis of (E)-styrylflavones through Wittig reactions, is also studied.
Treatment of B-ring substituted 5,7-dihydroxy flavones with alkyl halides in the presence of potassium carbonate gave unexpected 3-alkylated flavonoids. Related experiments were carried out to explain the formation of 3-alkylated flavonoids and a ring opening followed by alkylation and ring closure mechanism was proposed. (c) 2005 Elsevier Ltd.
