    Total Synthesis of Two Naphthoquinone Antibiotics, Psychorubrin and Pentalongin, and Their C(1)-Substituted Alkyl and Aryl Derivatives
    摘要:
    The synthesis of 1-alkyl- and 1-aryl-1H-naphtho[2,3-c]pyran-5,10-dione bearing a C(3)-C(4) double bond, was performed by two alternative cyclization strategies of 2,3-disubstituted 1,4-naphthoquinones. Lemieux-Johnson oxidation of 2-allyl-3-hydroxymethyl-1,4-dimethoxynaphthalenes and subsequent oxidative demethylation of the intermediate 3,4-dihydro-5,10-dimethoxy-1H-naphtho[2,3 -c]pyran-3-oles to the corresponding 3,4-dihydro-3-hydroxy-1H-naphtho[2,3-c]pyran-5, 10-diones gave, after acid-catalyzed dehydration, the de shed 1H-naphtho[2,3-c]pyran-5,10-diones. Alternatively, the pyranonaphthoquinone ring system was constructed by intramolecular acid-catalyzed condensation of(3-hydroxymethyl-1,4-naphthoquinone-2-yl)acetaldehyde acetals. Using this synthetic approach, the synthesis of two naturally occurring naphthoquinone antibiotics, pentalongin and psychorubrin, is reported.

  • Allylation of Quinones via Photoinduced Electron-Transfer Reactions from Allylstannanes
    作者:Kazuhiro Maruyama、Hiroshi Imahori
    DOI:10.1246/bcsj.62.816
    日期:1989.3
    Photochemical reactions of quinones with allylstannanes provided four types of products: adducts of allyl group to the carbonyl oxygens of quinones, adducts of allyl group to the olefinic carbons, adducts of allyl group to the carbonyl carbons, and hydroquinones. An electron-transfer mechanism was confirmed by 1H-CIDNP (Chemically Induced Dynamic Nuclear Polarization) method. This study suggests that
    醌与烯丙基锡烷的光化学反应提供了四种类型的产物:烯丙基与醌的羰基氧的加合物、烯丙基与烯烃碳的加合物、烯丙基与羰基碳的加合物和对苯二酚。通过1H-CIDNP(化学诱导动态核极化)方法证实了电子转移机制。该研究表明 a) 从烯丙基锡烷到醌的光致电子转移产生相应的醌阴离子自由基和锡阳离子自由基,b) 锡阳离子自由基裂解产生烯丙基自由基和锡阳离子,以及 c) 烯丙基自由基攻击醌阴离子自由基导致最终产物烯丙基化醌的形成。

    日期:1986.10.5
    Photochemical reactions of halogeno-quinones with allylstannane in a benzene or an acetonitrile solution afforded allylated quinones and allyl quinols as major products. Nuclear spin polarization effects observed during irradiation support a contribution of electron transfer process.

    The enantioselective synthesis of (1 R,3 R)-deoxynanaomycin A ( 4) is reported. The key step involves introduction of the stereocenter in ( S)-homoallylic alcohol 10A using an asymmetric allylation of aldehyde 9.
