  • Total synthesis and confirmation of the absolute stereochemistry of semiviriditoxin, a naphthopyranone metabolite from the fungus Paecilomyces variotii
    作者:Nichole P.H. Tan、Christopher D. Donner
    DOI:10.1016/j.tet.2009.03.016
    日期:2009.5
    The first total synthesis of (S)-semiviriditoxin 2 is described. The approach utilizes a tandem Michael–Dieckmann reaction between ortho-toluate 5 and dihydropyran-2-one 6 to construct the naphthopyranone core, the dihydropyran-2-one 6 being prepared from (R)-1,2-epoxy-4-butanol. Spectroscopic comparison of synthetic (S)-semiviriditoxin 2 with (R)-semivioxanthin 3, prepared in four steps from (R)-propylene
    描述了(S)-半viriditoxin 2的第一个全合成。该方法利用邻甲苯甲酸酯5和二氢吡喃-2-酮6之间的串联Michael-Dieckmann反应来构建萘吡喃酮核,二氢吡喃-2-酮6由(R)-1,2-环氧-4-丁醇制备。由(R)-环氧丙烷分四个步骤制得的合成(S)-半viriditoxin 2与(R)-semivioxanthin 3的光谱比较证实了天然半viriditoxin的(S)-立体化学拟青霉。
  • Flexible Tetrahydropyran Synthesis from Homopropargylic Alcohols Using Sequential Pd–Au Catalysis
    作者:Jungjoon Kim、Wook Jeong、Young Ho Rhee
    DOI:10.1021/acs.orglett.6b03532
    日期:2017.1.6
    flexible synthetic method toward highly substituted tetrahydropyran is reported. The key transformation involves atom-efficient sequential metal catalysis consisting of Pd-catalyzed addition of homopropargylic alcohols to alkoxyallene and the subsequent gold(I)-catalyzed cycloisomerization. Notably, this method gives access to both 2,6-cis- and 2,6-trans-tetrahydropyrans possessing diverse substitution patterns
    报道了一种针对高度取代的四氢吡喃的灵活的合成方法。关键的转变涉及原子有效的顺序金属催化,该催化由Pd催化的均丙醇加成到烷氧基丙二烯中,以及随后的Gold(I)催化的环异构化。值得注意的是,该方法可同时获得具有多种取代模式的2,6-顺式-和2,6-反式-四氢吡喃。
  • Synthesis of the Griseusin B Framework via a One-Pot Annulation–Methylation–Double Deprotection–Spirocyclization Sequence
    作者:Briar J. Naysmith、Margaret A. Brimble
    DOI:10.1021/ol400686f
    日期:2013.4.19
    A highly convergent synthesis of the griseusin B scaffold is described. The key step involves an efficient one-pot Hauser–Kraus annulation–methylation–double deprotection–spirocyclization sequence that directly affords the target parent tetracyclic ring system.
    描述了灰黄霉素B支架的高度收敛的合成。关键步骤涉及有效的一锅式Hauser-Kraus环化-甲基化-双重脱保护-螺环化序列,该序列直接提供了目标母体四环系统。
  • The second generation synthesis of (+)-pseudodeflectusin
    作者:Yuna Sato、Kouji Kuramochi、Takahiro Suzuki、Atsuo Nakazaki、Susumu Kobayashi
    DOI:10.1016/j.tetlet.2010.11.153
    日期:2011.2
    The second generation synthesis of (+)-pseudodeflectusin (1), a potential antitumor agent, has been achieved. The key synthetic step is the cascade reaction involving Diels-Alder reaction, lactonization, and decarboxylation to give cycloadduct 6 with complete regioselectivity in good yield. We found that NaH is the best base to facilitate the Diels-Alder reaction of hydroxypyrone 7 with alkyne 8. The present synthetic route enables the total synthesis of (+)-1 in only five-steps from the known compounds 7 and 8. (C) 2010 Elsevier Ltd. All rights reserved.
  • Stereoselective Total Synthesis of Multiplolide A and of a Diastereoisomer
    作者:Bandi Chennakesava Reddy、Vikas Madhukar Bangade、Palakuri Ramesh、Harshadas Mitaram Meshram
    DOI:10.1002/hlca.201200164
    日期:2013.2
    A stereoselective total synthesis of multiplolide A (1) and of its diastereoisomer 2 was described from easily accessible starting materials (Schemes 2–4). The synthetic strategy involves a Jacobsen resolution, Sharpless epoxidation, Swern oxidation, Yamaguchi reaction, and ring‐closing metathesis (RCM).
    multiplolide A(的立体选择性全合成1)和对映异构体及其2是从容易获得的起始原料描述(方案2 - 4)。合成策略包括Jacobsen拆分,Sharpless环氧化,Swern氧化,Yamaguchi反应和闭环复分解(RCM)。
