    摘要:
    Cochinellic酐甲基,乙基和苄基酯(4-甲氧基-4-乙氧基和4-苄氧基-羰基-5-羟基-3-甲基邻苯二甲酸酐)是通过2-溴马来酸酐与2-溴马来酸酐的单阶段狄尔斯-阿尔德反应制备的3-烷氧基羰基-2,4-双(三甲基甲硅烷氧基)戊-1,3-二烯。通过类似的加成反应,但与3-乙氧基羰基-2-甲氧基-4-三甲基甲硅烷基氧基戊-1,3-二烯一起获得了相应的5-甲基醚乙酯。在三氟化硼-二乙醚与椰油酰胺酐甲酯的存在下,通过1,4-二甲氧基苯的酰化反应合成6-脱氧kermes甲酯是不成功的。首选途径是通过Diels-Alder将3-烷氧基羰基-2,4-双(三甲基甲硅烷基氧基)戊-1,3-二烯添加到萘他林(或2-氯萘他林)中。六-脱氧kermes的四乙酸铅氧化得到双(醌),其Thiele乙酰氧基化在水解和过甲基化后产生等比例的kermes酸和isokermes酸的衍生物的混合物。Diels–Alde

    The first synthesis of carminic acid (7β-D-glucopyranosyl-3,5,6,8-tetrahydroxy-1-methyl-9,10-dioxo-9,10-dihydroanthracene-2-carboxylic acid) is described. Selective C-glycosylation at the 7-position of ethyl and benzyl 3,5,8,9,10-pentamethoxy-1-methylanthracene-2-carboxylates with 2,3,4,6-tetra-O-benzyl-1-trifluoroacetyl-α-D-glucopyranose afforded intermediates which were oxidised to ethyl and benzyl 3,5,8-trimethoxy-1-methyl-9,10-dioxo-7-(2′,3′,4′,6′-tetra-O-benzyl-β-D-glucopyranosyl)-9,10-dihydroanthracene-2-carboxylate respectively. The benzyl compound was hydrogenolysed and the ethyl analogue hydrogenolysed and hydrolysed to give the same product, which was tetraacetylated and demethylated to afford 6-deoxycarminic acid tetraacetate, 3,5,8-trihydroxy-1-methyl-9,10-dioxo-7-(2′,3′,4′,6′-tetra-O-acetyl-β-D-glucopyranosyl)-9,10-dihydroanthracene-2-carboxylic acid. The pentamethoxy intermediates were obtained from 2-chloronaphthazarin by Diels–Alder addition to 3-alkoxycarbonyl-2,4-bis(trimethylsiloxy)penta-2,4-dienes to give alkyl 6-deoxykermesates. Methylation afforded the corresponding trimethyl ethers, which by reductive methylation gave the required pentamethoxy compounds. By known steps 6-deoxycarminic acid tetraacetate was converted into the 5,8,9,10-bisquinone, acetoxylation of which gave carminic acid octaacetate. Acidic hydrolysis afforded carminic acid.
    首次合成了胭脂酸(7β-D-葡萄糖吡喃糖基-3,5,6,8-四羟基-1-甲基-9,10-二氧基-9,10-二氢蒽-2-羧酸)。选择性地在乙基和苄基3,5,8,9,10-五甲氧基-1-甲基蒽-2-羧酸酯的7位进行C-糖苷化,与2,3,4,6-四-O-苄基-1-三氟乙酰-α-D-葡萄糖吡喃糖反应得到了中间体,随后氧化得到乙基和苄基3,5,8-三甲氧基-1-甲基-9,10-二氧基-7-(2′,3′,4′,6′-四-O-苄基-β-D-葡萄糖吡喃糖)-9,10-二氢蒽-2-羧酸酯。苄基化合物经过氢解,乙基类似物经过氢解和水解,得到了相同的产物,然后进行四乙酰化和脱甲基反应,得到6-脱氧胭脂酸四乙酸酯,即3,5,8-三羟基-1-甲基-9,10-二氧基-7-(2′,3′,4′,6′-四-O-乙酰-β-D-葡萄糖吡喃糖)-9,10-二氢蒽-2-羧酸。五甲氧基中间体是通过将2-氯萘扎林与3-烷氧基羧基-2,4-双(trimethylsiloxy)戊-2,4-二烯进行Diels-Alder反应获得的,以得到烷基6-脱氧克尔梅酸酯。甲基化反应产生相应的三甲基醚,经过还原甲基化得到所需的五甲氧基化合物。通过已知步骤,6-脱氧胭脂酸四乙酸酯被转化为5,8,9,10-双醌,进一步的醋酸化反应得到胭脂酸八乙酸酯。酸性水解反应得到胭脂酸。

    日期:2008.4
    Methodology has been sought towards obtaining a 2-chloro-1,4-naphthoquinone bearing hydroxyl groups in the adjoining ring for obtaining either kermesic or carminic acids. In the first of these objectives, kermesic acid has been synthesised from 6-chloro-2,5,8-trihydroxynaphtho-1,4-quinone by the regioselective cycloaddition of the 1,2-diacetate formed by its acetylation-aided tautomerism and cycloaddition

  • Synthesis of tetracenomycins
    作者:Donald W. Cameron、Pauline J. de Bruyn
    DOI:10.1016/s0040-4039(00)61155-3
    日期:1992.9
    Tetracenomycins D, A2, B1 and B2 (2)-(5) have been synthesised for the first time, by an efficient, regioselective sequence based on cycloaddition methodology; the ambiguity that existed for tetracenomycins B1 and B2 has thereby been resolved in favour of structures (4a) and (5b) respectively.
