  Synthesis of Deuterated γ-Lactones for Use in Stable Isotope Dilution Assays

  摘要：

  Two syntheses of deuterated gamma-lactones for use as internal standards in stable isotope dilution assays (SIDA) were developed. [2,2,3,3-H-2(4)]-gamma-Octa-, -gamma-deca-, and -gamma-dodecalactones with > 89% deuterium incorporation were prepared in 27, 17, and 19% overall yields, respectively, by the reduction of a doubly protected hydroxypropiolic acid with deuterium gas. [3,3,4-H-2(3)]-gamma-Octa- and -gamma-dodecalactones were prepared in 6 and 23% yields with > 92% deuterium incorporation by the free radical addition of 2-iodoacetamide to [1,1,2-H-2(3)]-1-hexene and [1,1,2-H-2(3)]-1-decene, respectively. Reaction yields were highly dependent upon the purity of the 1-alkene starting material. The deuterated gamma-lactones were evaluated as internal standards for SIDA.

• Mg(OMe)₂ promoted allylic isomerization of γ-hydroxy-α,β-alkenoic esters to synthesize γ-ketone esters

  日期：——

  This work concerns the Mg(OMe)2 promoted allylic isomerization of γ-hydroxy-α,β-alkenoic esters with TMEDA as an additive. The isomerization proceeded under mild conditions and afforded γ-keto esters in high yield (up to 96%) within 2 h. Both (Z)- and (E)-γ-hydroxy-α,β-alkenoic esters were tolerated under the reaction conditions. This transformation involves the in situ formation of a dienolate intermediate

  这项工作涉及以TMEDA作为添加剂的Mg（OMe）2促进的γ-羟基-α，β-链烯酸酯的烯丙基异构化。异构化在温和的条件下进行，并在2小时内以高收率（高达96％）提供了γ-酮酯。在反应条件下，（Z）-和（E）-γ-羟基-α，β-链烯酸酯均被耐受。该转化涉及从容易获得的γ-羟基-α，β-链烯酸酯原位形成二烯酸酯中间体。该原位生成的二烯醇酯可以与苯甲醛反应并经历一种实用，有用的串联烯丙基异构化-羟醛反应，得到更多官能的化合物。
• A Redox Economical Synthesis of Bioactive 6,12-Guaianolides

  Syntheses of two 6,12-guaianolide analogs are reported within. The scope of the tandem allylboration/lactonization chemistry is expanded to provide a functionalized allene-yne-containing alpha-methylene butyrolactone that undergoes a Rh(I)-catalyzed cyclocarbonylation reaction to afford a 5-7-5 ring system. The resulting cycloadducts bear a structural resemblance to other NF-kappa B inhibitors such as cumambrin A and indeed were shown to inhibit NF-kappa B signaling and cancer cell growth.
