A subsequent retro [2 + 2] cycloaddition/6 pi elect... Versatile Introduction of Azido Moiety into Oligonucleotides through Diazo Transfer Reaction [作者：LARTIA REMY; MURAT PIERRE; DUMY PASCAL; DEFRANCQ ERIC,期刊：Organic Letters, 页码：5672-5675 , 文章类型： Article，,卷期：2011年13-20] The use of a diazo transfer (DZT) reagent enables clean and efficient conversion of aminated oligodeoxyribonucieotides (ODNs) into their azido counterparts under mild conditions. ODNs bearing an amino tether at the 3', 5... Modular Approach to Saturated and alpha,beta-Unsaturated Ketones [作者：DEBIEN LAURENT; QUICLETSIRE BEATRICE; ZARD SAMIR Z,期刊：Organic Letters, 页码：5676-5679 , 文章类型： Article，,卷期：2011年13-20] 2-Fluoro-6-pyridinyloxy derivatives of 2-ethoxyvinyl carbinois react with radicals derived from xanthates by an addition fragmentation pathway to give highly functionalized ketones after acid hydrolysis. 1,4-Diketones ar... Aryl Aldehydes as Traceless Dielectrophiles in Bifunctional Titanocene-Catalyzed Propargylic C-X Activations [作者：CAMPOS CATHERINE A; GIANINO JOSEPH B; PINKERTON DAVID M; ASHFELD BRANDON L,期刊：Organic Letters, 页码：5680-5683 , 文章类型： Article，,卷期：2011年13-20] The titanocene-catalyzed construction of all-carbon substituted tertiary centers directly from aromatic aldehydes is described. The starting aldehyde behaves as a traceless functionality in the formation of multiple carb... Highly Diastereoselective and General Synthesis of Primary beta-Fluoroamines [作者：SCHULTE MICHAEL L; LINDSLEY CRAIG W,期刊：Organic Letters, 页码：5684-5687 , 文章类型： Article，,卷期：2011年13-20] A short, high yielding protocol has been developed for the highly diastereoselective (dr >20:1) and general synthesis of primary beta-fluoroamines by the enantioselective alpha-fluorination of aldehydes, conversion into ... Formation of 1:2 Host-Guest Complexes Based on Triptycene-Derived Macrotricycle and Paraquat Derivatives: Anion-pi Interactions between PF(6)(-) and Bipyridinium Rings in the Solid State [作者：GUO JIABIN; HAN YING; CAO JING; CHEN CHUANFENG,期刊：Organic Letters, 页码：5688-5691 , 文章类型： Article，,卷期：2011年13-20] A triptycene-derived macrotricyclic host containing two dibenzo-[30]-crown-10 moieties forms stable 1:2 host-guest complexes with paraquat derivatives in both solution and the solid state, in which anion-pi interactions ... Anthraceno-Perylene Bisimides: The Precursor of a New Acene [作者：LI YONGJUN; XU LIANG; LIU TAIFENG; YU YANWEN; LIU HUIBIAO; LI YULIANG; ZHU DAOBEN,期刊：Organic Letters, 页码：5692-5695 , 文章类型： Article，,卷期：2011年13-20] A controlled synthesis strategy for a anthracene-fused perylene bisimide was developed from the cyclization of an anthracene unit pendant to a perylene diimide scaffold. The direct cyclization led to a zigzag molecule, w... Toward the Synthesis of Norzoanthamine: Building Carbocyclic Core by a Transannular Michael Reaction Cascade [作者：XUE HAORAN; YANG JIONG; GOPAL PEDDABUDDI,期刊：Organic Letters, 页码：5696-5699 , 文章类型： Article，,卷期：2011年13-20] A 12-step synthesis of the ABC carbocyclic core of norzoanthamine is described.
