  • Synthesis of the Reported Structure of Crassiflorone, a Pentacyclic Naphthoquinone Isolated from the African Ebony Diospyros crassiflora
    作者:Christopher Moody、Jalindar Padwal、William Lewis
    DOI:10.1055/s-0029-1218578
    日期:2010.3
    A short synthesis of the furocoumarin naphthoquinone structure reported for the natural product crassiflorone is descnbed, in which the key steps are a Diels-Alder reaction to form 2-bromo-8-hydroxy-6-methylnaphthoquinone, followed by O-protection and copper(II)-mediated coupling to 4-hydroxy-5-methylcoumarin to establish the pentacyclic framework.
    描述了天然产物紫花酮的呋喃香豆素萘醌结构的简短合成,其中关键步骤是狄尔斯-阿尔德反应形成 2-溴-8-羟基-6-甲基萘醌,然后是 O-保护和铜( II) 介导的与 4-羟基-5-甲基香豆素的偶联以建立五环框架。
  • Synthesis of the reported structure of crassiflorone, a naturally occurring quinone isolated from the African ebony Diospyros crassiflora, and regioisomeric pentacyclic furocoumarin naphthoquinones
    作者:Jalindar Padwal、William Lewis、Christopher J. Moody

    日期:——
    The key steps are a Diels–Alder reaction to form 2-bromo-8-hydroxy-6-methylnaphthoquinone, followed by O-protection and copper(II) mediated coupling to 4-hydroxy-5-methylcoumarin to establish the pentacyclic framework whose structure was unambiguously confirmed by X-ray crystallography. Since the spectroscopic data of the synthetic material did not match those reported for the natural product, three
    描述了报道的天然产物crassiflorone(呋喃香豆素萘醌)的结构合成。关键步骤是形成狄尔斯-阿尔德反应2-溴-8-羟基-6-甲基萘醌然后进行O保护和铜(II)介导的偶联4-羟基-5-甲基香豆素建立五环骨架,其结构已通过X射线晶体学明确证实。由于合成材料的光谱数据与天然产物的光谱数据不匹配,因此另外三个区域异构体呋喃香豆素萘醌是通过铜(II)介导的4-羟基-5-或8-甲基香豆素与5-苄氧基-2-溴-7-甲基-或8-苄氧基-2-溴-6-甲基-1的偶联而制备的, 4-萘醌。再次,光谱数据与天然物质的光谱数据不匹配,因此,卡西花酮的真实结构仍是未知的。
  • Silver(I)/celite promoted oxidative cycloaddition of 4-hydroxycoumarin to olefins. A facile synthesis of dihydrofurocoumarins and furocoumarins

    日期:1998.10
    An efficient synthesis of dihydrofurocoumarins and furocoumarins is achieved from 4-hydroxycoumarins and olefins in the presence of Ag2CO3/Celite in moderate yields. The new method has been applied to the synthesis of the natural cyclobrachycoumarin isolated from Brachyclados megalanthus.

    The unusual alcohol mediated formation of 4-oxo-2-aryl-4H-chromene-3-carboxylate (flavone-3-carboxylate) derivatives from 4-hydroxycoumarins and β-nitroalkenes in an alcoholic medium is described. The transformation occurs via the in situ formation of a Michael adduct, followed by the alkoxide ion mediated rearrangement of the intermediate. The effect of the different alcohol and nonalcohol media on

    An efficient approach was developed for synthesis of 3-tosyloxy-4-hydroxycoumarins under mild conditions by using Koser’s reagents. The reaction tolerated various functional groups, and the products served as useful aromatic building blocks. Additionally, a plausible mechanism via iodonium ylide was proposed, and the oral anticoagulant Warfarin was synthesized in good yield.
