  Total Synthesis of the Antitumor–Antitubercular 2,6′-Bijuglone Natural Product Diospyrin and Its 3,6′-Isomer

  摘要：

  The 2,6'-bijuglone natural product diospyrin and its unnatural 3,6'-isomer idospyrin have been synthesized in seven steps each from N,N-diethylsenecioamide in overall yields of 12% and 13%, respectively. The syntheses diverge from ramentaceone (7-methyljuglone) and include a key Suzuki-Miyaura cross-coupling. Diospyrin, idospyrin, and several synthetic precursors exhibit potent and selective cytotoxicity to the murine myeloma NS-1 cell line over neonatal foreskin cells.

• γ-Silylated α,β-unsaturated amides — Preparation by [1,5]-sigmatropic rearrangement and use as masked dienolate equivalents in carbonyl condensations

  The reaction of lithium dienolates derived from N,N-dialkylsenecioamides (1a–1c) with triorganosilyl electrophiles occurs initially at the oxygen atom predominantly, and is followed by an O → C silicon migration to afford the γ-silylated senecioamides (4a–4h). The γ-silylated senecioamide Z-4a undergoes fluoride-ion-mediated condensations with aromatic aldehydes to give kinetic α-(6) and thermodynamic γ-(5) condensation product patterns comparable to lithium dienolates. The TiCl₄-mediated reactions with aldehydes gives α-products (6) in a highly syn-selective manner. Possible transition-state models for the syn-selective condensations are discussed and a chair-like transition state featuring bidentate coordination to titanium (11) is proposed.

  The reaction of lithated N, N-diethylsenecioamide and N, N-diethy-3-phenlisocrotonamide with methoxy-substituted benzynes, generated in situ from methoxy-substituted halobenzenes, gave regiospecifically various 3-methyl- and 3-phenyl-naphthol derivatives in a one-pot process. Methoxy-substituted 3-methyl-1-naphthols thus obtained were easily converted into various 1, 4-naphthoquinones and 1, 2-naphthoquinones including biologically active natural products such as plumbagin, plumbagin methylether, 5, 6-dimethoxy-2-methyl-1, 4-naphthoquinone, and 8-methoxy-3-mathyl-1, 2-naphthoquinone.

  The novel reagents formed by combination of Grignard reagents (RMgX) with lithium diisopropylamide (LDA) convert non-enolizable or slowly enolizable carboxylic esters or caboxamides into ketones which are protected from further reaction by their in situ conversion into enolates. These enolates can be trapped with electrophiles such as Me3SiCl and allyl bromide. The scope of this Grignard mono-addition

  由格氏试剂（RMgX）与二异丙基氨基化锂（LDA）结合形成的新型试剂可将不可烯化或缓慢可烯化的羧酸酯或羧酰胺转化为酮，可通过原位转化为烯醇酸酯来防止其进一步反应。这些烯醇化物可以被亲电试剂（例如Me 3 SiCl和烯丙基溴）捕获。这种格氏试剂单加成的范围由蒿蒿酮的两种直接合成方法说明（14）。

• Palladium-Catalyzed Double and Single Carbonylation of Aryl Halides and Allylic Compounds
  作者：Akio Yamamoto

  DOI：10.1246/bcsj.68.433

  日期：1995.2

  After a brief introduction summarizing the author’s previous work concerning the double carbonylation of aryl halides catalyzed by palladium complexes, newly found catalytic processes (1) for converting allylic formates and chlorides into β,γ-unsaturated acids and (2) the double carbonylation of allylic chlorides to β,γ-unsaturated α-keto amides are described. Mechanisms which reasonably account for the catalytic processes are proposed on the basis of studies concerning the properties of the organopalladium complexes.
