They were found to act as effective ligands in the Pd-catalyzed allylic alkylation reactions. Using these ligand... 1,3-Oxazinan-2-ones from Amines and 1,3-Diols through Dialkyl Carbonate Chemistry [作者：MCELROY CON ROBERT; ARICO FABIO; TUNDO PIETRO,期刊：SYNLETT, 页码：1809-1815 , 文章类型： Article，,卷期：2012年-12] A one-pot green synthesis of 1,3-oxazinan-2-ones from amines and 1,3-diols in the presence of a dialkyl carbonate and potassium tert-butoxide is described. Four dialkyl carbonates were utilised: dimethyl carbonate, dieth... Synthesis of 3-Substituted 2-Aminopyridines via Displacement of 3-Fluoro-2-nitropyridine [作者：CULSHAW JANET D; EDEN JONATHAN M; FORD SUSANNAH J; HAYTER BARRY; PERKINS DAVID R; PIKE KURT G,期刊：SYNLETT, 页码：1816-1820 , 文章类型： Article，,卷期：2012年-12] An efficient method for the substitution of 3-fluoro-2-nitropyridine with a range of nitrogen-containing heterocycles and aliphatic amines is described. The reaction proceeds in a regioselective manner at moderate temper... Development of a Dual Fries-Claisen Rearrangement Strategy [作者：DUFFY LIAM J; GARCIATORRES JASON; JONES RAYMOND C F; ALLIN STEVEN M,期刊：SYNLETT, 页码：1821-1823 , 文章类型： Article，,卷期：2012年-12] In this paper we describe the development and application of a sequential Fries-Claisen rearrangement strategy as a new route for annelation on an aromatic ring. We demonstrate the potential utility of this protocol thro... A Bidirectional Synthesis of (+)-Terreusinone [作者：WANG CHRISTY; SPERRY JONATHAN,期刊：SYNLETT, 页码：1824-1828 , 文章类型： Article，,卷期：2012年-12] An efficient, bidirectional synthesis of the photoprotecting dipyrrolobenzoquinone (+)-terreusinone has been accomplished. Key steps include a copper-and amine-free double Sonogashira reaction of an electron-rich 1,4-dib... An Efficient Synthesis of Allosamidin [作者：HUANG GANGLIANG; SHU SHUANGQUAN,期刊：SYNLETT, 页码：1829-1831 , 文章类型： Article，,卷期：2012年-12] The solid-phase synthesis of allosamidin was investigated. After two N-benzyloxycarbonyl (Cbz)-protected trichloroacetimidate donors were synthesized, the solid-phase synthesis was performed using polystyrene as support ... Asymmetric Total Synthesis of ent-Tetrahydrolipstatin from an Epoxy Alkenol [作者：KIM HYEMI; CHOI KYEONGHWAN; TAE JINSUNG,期刊：SYNLETT, 页码：1832-1834 , 文章类型： Article，,卷期：2012年-12] A highly efficient asymmetric total synthesis of ent-tetrahydrolipstatin (THL) was accomplished from the known epoxy alkenol. The beta-lactone portion of THL was synthesized by the epoxide opening with cyanide and stereo... Synthesis of alpha,beta '- and beta,beta '-Linked Dimethoxycarbonyldipyrromethanes by Rothemund-Type Condensation [作者：JOURNOT GUILLAUME; STOECKLIEVANS HELEN; NEIER REINHARD,期刊：SYNLETT, 页码：1835-1839 , 文章类型： Article，,卷期：2012年-12] The Rothemund-type condensation of methoxycarbonyl-pyrrole with acetone produces mainly the alpha,beta'-linked dipyrromethane, a building block for the synthesis of N-confused macrocycles. The influence of the reaction c... Monitoring Biocatalytic Transformations Mediated by Polyketide Synthase Enzymes in Cell Lysate via Fluorine NMR [作者：PIASECKI SHAWN K; KEATINGECLAY ADRIAN T,期刊：SYNLETT, 页码：1840-1842 , 文章类型： Article，,卷期：2012年-12] The biocatalytic employment of modular polyketide synthase enzymes in cell lysate has become a viable route to preparative quantities of synthetically valuable polyketide fragments. We report the quantitative, uninvasive... Potent Oligomerization and Macrocyclization Activity of the Thioesterase Domain of Vicenistatin Polyketide Synthase [作者：KUDO FUMITAKA; ASOU YUSAKU; WATANABE MOE; KITAYAMA TAKASHI; EGUCHI TADASHI,期刊：SYNLETT, 页码：1843-1846 , 文章类型： Article，,卷期：2012年-12] The thioesterase domain of the polyketide synthase involved in the biosynthesis of the 20-membered macrolactam antibiotic vicenistatin (VinTE) was found to catalyze oligomerization and macrocyclization of omega-hydroxy f... Sodium Selenide [作者：GUO RUIYUN,期刊：SYNLETT, 页码：1847-1848 , 文章类型： Editorial Material，,卷期：2012年-12] 1-{[1-(Cyano-2-ethoxy-2-oxoethylidenaminooxy)dimethylaminomorpholinometh ylene]}methaneaminium hexafluorophosphate [作者：BERGUEIRO ALVAREZ JULIAN,期刊：SYNLETT, 页码：1849-1850 , 文章类型： Editorial Material，,卷期：2012年-12]
