[作者：Carrick, Jesse D.;Jennings, Michael P.;,期刊：Organic Letters, 页码：769-772 , 文章类型： 研究论文，,卷期：2009年11-3] The enantioselective formal synthesis of the polyketide marine natural product (-)-clavosolide A is presented. The construction of the b-C-glycoside subunit I is highlighted by a one-pot oxocarbenium cation formation/re... Palladium-Catalyzed Sequential Arylation and Allylic Alkylation of Highly Functionalized Ketones: A Concise Synthesis of Mesembrine. [作者：Zhao, Yuanhong;Zhou, Yongyun;Liang, Leilei;Yang, Xiaodong;Du, Fengxiang;Li, Liang;Zhang, Hongbin;,期刊：Organic Letters, 页码：555-558 , 文章类型： 研究论文，,卷期：2009年11-3] An unprecedented palladium-catalyzed sequential procedure toward arylation and allylic alkylation of highly functionalized cyclohexenones was developed. This new protocol leads to useful building blocks contg. a benzyli... Novel Synthesis of a 1,3,5-Trioxazatriquinane Skeleton Using a Nitrogen Clamp. [作者：Nagase, Hiroshi;Watanabe, Akio;Harada, Masaya;Nakajima, Mayumi;Hasebe, Ko;Mochizuki, Hidenori;Yoza, Kenji;Fujii, Hideaki;,期刊：Organic Letters, 页码：539-542 , 文章类型： 研究论文，,卷期：2009年11-3] An a-hydroxyaldehyde derived from naltrexone (I) was converted to oxazoline dimer II with ammonium chloride and sodium acetate in MeOH under reflux. The resulting dimer was treated with dl-camphorsulfonic acid in CHCl3 ... Biomimetic Synthesis toward the Transtaganolides/Basiliolides. [作者：Larsson, Rikard;Sterner, Olov;Johansson, Martin;,期刊：Organic Letters, 页码：657-660 , 文章类型： 研究论文，,卷期：2009年11-3] reaction sequence suggesting the involvement of pericyclic reactions in the biosynthesis of these biol. active plant metabolites was presented. Geraniol ester I [R = CH2CO2CH2CH:CMe(CH2)2CH:CMe2-(E)] underwent rearrangem... Preparation of Bicyclic 1,2,4-Trioxanes from g,d-Unsaturated Ketones.

A.;,期刊：Organic Letters, 页码：507-510 , 文章类型： 研究论文，,卷期：2009年11-3] Treatment of g,d-unsatd. ketones with hydrogen peroxide and acid provides a rapid entry into the medicinally important 1,2,4-trioxane structure, e.g., I. Alkene substitution that stabilizes carbocationic intermediates p... Orthogonal Synthesis of Isoindole and Isoquinoline Derivatives from Organic Azides. [作者：Hui, Benjamin Wei-Qiang;Chiba, Shunsuke;,期刊：Organic Letters, 页码：729-732 , 文章类型： 研究论文，,卷期：2009年11-3] a-Azido carbonyl compds. bearing a 2-alkenylaryl moiety at the a-position are found to be promising precursors for synthesis of isoindole and isoquinoline derivs. via 1,3-dipolar cycloaddn. of azides onto alkenes and 6p-... Cascade Palladium-Catalyzed Alkenyl Aminocarbonylation/ Intramolecular Aryl Amidation: An Annulative Synthesis of 2-Quinolones. [作者：Tadd, Andrew C.;Matsuno, Ai;Fielding, Mark R.;Willis, Michael C.;,期刊：Organic Letters, 页码：583-586 , 文章类型： 研究论文，,卷期：2009年11-3] Palladium-catalyzed intermol. aminocarbonylation/intramol. amidation cascade sequences can be used to convert a range of 2-(2-haloalkenyl)aryl halide substrates efficiently and selectively to the corresponding 2-quinolon... Novel Chiral Molecular Tweezer from (+)-Usnic Acid. [作者：Legouin, Beatrice;Uriac, Philippe;Tomasi, Sophie;Toupet, Loic;Bondon, Arnaud;van de Weghe, Pierre;,期刊：Organic Letters, 页码：745-748 , 文章类型： 研究论文，,卷期：2009年11-3] A new chiral mol. tweezer was synthesized with (1R,2R)-1,2-diaminocyclohexane as spacer and two mols. of (+)-usnic acid as pincers. The ability of this mol. tweezer to bind 2,4,7-trinitrofluorenone (TNF) was studied. A... A Novel Approach to the CDE Ring System of Pectenotoxin-4 Triggered by VO(acac)2-Induced Epoxy-Acetalization. [作者：Carley, Sarah;Brimble, Margaret A.;,期刊：Organic Letters, 页码：563-566 , 文章类型： 研究论文，,卷期：2009年11-3] induced by VO(acac)2 epoxidn. of a homoallylic alc. Spongistatin synthetic studies.
