  • Synthesis of pyranoisoflavones by the oxidative rearrangement of dihydropyranochalcones with thallium(III) Nitrate: Synthesis of elongatin, its angular isomer, toxicarol isoflavone, and related compounds.

    Elongatin, 4', 5-dihydroxy-2', 5'-dimethoxy-2", 2"-dimethylpyrano[5", 6"-g]isoflavone (1), was prepared by the oxidative rearrangement of 6'-acetoxy-2', 4-bis(benzyloxy)-2, 5-dimethoxy-2", 2"-dimethyldihydropyrano[5", 6"-c]chalcone (15) with thallium(III) nitrate and by dehy-drogenation of the resultant linear 4', 5-dihydroxy-2', 5'-dimethoxy-2", 2"-dimethyldihydropyrano-[5", 6"-g]isoflavone (19) with 2, 3-dichloro-5, 6-dicyano-1, 4-benzoquinone. Its angular isomer, 4', 5-dihydroxy-2', 5'-dimethoxy-2", 2"-dimethylpyrano[6", 5"-h]isoflavone (2), was also synthesized from the corresponding chalcone (28) in a similar manner and then converted into toxicarol isoflavone (3).

  • Nuclear isoprenylation of polyhydroxyacetophenones
    作者:V.K. Ahluwalia、K.K. Arora
    DOI:10.1016/s0040-4020(01)92463-9
    日期:1981.1
    A novel method of nuclear isoprenylation leading to the exclusive formation of 2,2-dimethylchromans has been achieved by the direct condensation of polyhydroxyacetophenones with isoprene in presence of phosphoric acid. Acetylchromans, thus obtained, are dehydrogenated with DDQ to given corresponding 2,2-dimethylchromenes. Using this method, synthesis of number of naturally occurring chromenes, viz
    通过在磷酸的存在下聚羟基苯乙酮与异戊二烯的直​​接缩合,已经实现了导致异戊二烯仅形成2,2-二甲基苯并二氢吡喃的新型核异戊烯化方法。将如此获得的乙酰基苯并二氢吡喃酮用DDQ脱氢,得到相应的2,2-二甲基苯并二苯甲基。使用这种方法,可以合成许多天然存在的色烯。ripariochromene A(6),eupatoriochromene(10),encecalin(11),isoevodionol(16),evodionol(17)和甲基evodionol(18)已受影响。
