2-Hydroxy-3,4′-dimethoxybibenzyl (=pellepiphyllin) and 3,4′-dihydroxybibenzyl (=lunularin) have been synthesized by Wittig type reactions. Condensation of 2,3-dimethoxybenzaldehyde with 4-methoxybenzylphosphonate to 2,3,4′ trimethoxystibene, catalytic reduction to 2,3,4′-trimethoxybibenzyl, demethylation to 2,3,4′-trihydroxybibenzyl and partial methylation yields pellepiphyllin. Lunularin was synthesized
通过Wittig型反应合成了2-羟基-3,4'-二甲氧基联苄基(=叶绿素)和3,4'-二羟基联苄基(lunulain)。2,3-二甲氧基苯甲醛与4-甲氧基苄基膦酸酯缩合为2,3,4'-三甲氧基sti,催化还原为2,3,4'-三甲氧基联苄,脱甲基为2,3,4'-三羟基联苄和部分甲基化产生蝶草素。通过使3-甲氧基苯甲醛与4-甲氧基苄基膦酸酯反应成3,4'-二甲氧基,,催化氢化成3,4'-二甲氧基联苄,并用三溴化硼脱甲基,来合成Lunularin。
