[作者：Drabowicz, Jozef;Kwiatkowska, Malgorzata;Kielbasinski, Piotr;,期刊：Synthesis, 页码：3563-3564 , 文章类型： 研究论文，,卷期：2008年-22] Alkyl arenesulfinates and S-thiosulfinates are readily accessible in good yields by the reaction of sulfinic acids and alcs. or thiols, resp., in the presence of lanthanide(III) triflates as catalysts. Design of an axially chiral dicarboxylic acid and its application in syntheses of optically active b-amino acids and b-amino phosphonic acid derivatives. [作者：Hashimoto, Takuya;Maruoka, Keiji;,期刊：Synthesis, 页码：3703-3706 , 文章类型： 研究论文，,卷期：2008年-22] An axially chiral dicarboxylic acid was developed as a new chiral Bronsted acid catalyst. With this novel catalyst in hand, N-Boc-protected b-amino acids or b-amino phosphonic acid derivs. could be obtained in high yiel... Carbon tetrabromide promoted reaction of amines with carbon disulfide: facile and efficient synthesis of thioureas and thiuram disulfides. [作者：Liang, Fushun;Tan, Jing;Piao, Chengri;Liu, Qun;,期刊：Synthesis, 页码：3579-3584 , 文章类型： 研究论文，,卷期：2008年-22] A novel carbon tetrabromide promoted one-pot reaction of amines and carbon disulfide under mild conditions has been developed, which provides a straightforward and efficient access to thioureas and thiuram disufides, dep... Primary alkyl bromides from dimethylthiocarbamates. [作者：Moynihan, Meghan F.;Tucker, Joseph W.;Abelt, Christopher J.;,期刊：Synthesis, 页码：3565-3568 , 文章类型： 研究论文，,卷期：2008年-22] The conversion of primary alkyl dimethylthiocarbamates into alkyl bromides using the Vilsmeier reagent occurs in high yields in the presence of other non-acid sensitive and non-nucleophilic functional groups. A convenient allylic functionalization of bis(prop-2-enyl)methanol by direct trimetalation. [作者：Bigot, Aurelien;Breit, Bernhard;,期刊：Synthesis, 页码：3692-3696 , 文章类型： 研究论文，,卷期：2008年-22] A practical synthesis of functionalized sym. dialkenylcarbinols has been developed. Key feature is a direct trilithiation of readily available bis(prop-2-enyl)methanol followed by trapping of the trianion with various e... Towards metformin prodrugs. [作者：Huttunen, Kristiina M.;Leppanen, Jukka;Kemppainen, Eeva;Palonen, Piia;Rautio, Jarkko;Jarvinen, Tomi;Vepsalainen, Jouko;,期刊：Synthesis, 页码：3619-3624 , 文章类型： 研究论文，,卷期：2008年-22] The first examples of possible metformin prodrugs have been synthesized and characterized by spectroscopic methods. These five different types of chem. stable prodrugs were prepd. from metformin and the corresponding ha... Synthesis of 2,3-dihydroxyhex-4-enoates by palladium-catalyzed allylic alkylations of carbohydrate derived vinyl lactones. [作者：Singleton, Jamie;Sahteli, Krishna;Hoberg, John O.;,期刊：Synthesis, 页码：3682-3686 , 文章类型： 研究论文，,卷期：2008年-22] D-Gulonic lactone or its L-isomer is easily converted to the vinyl lactone I via 3 convenient reactions in an overall 69% yield. Reaction of the D isomer of I with a variety of C-, O-, S-, and N nucleophiles and a Pd ca... Cobalt-catalysed carbon-carbon bond formation reactions. [作者：Hess, Wilfried;Treutwein, Jonas;Hilt, Gerhard;,期刊：Synthesis, 页码：3537-3562 , 文章类型： 综述，,卷期：2008年-22] A review. The recent developments in cobalt catalysis were compiled in this review covering the years 2000 through 2007. Special focus was directed towards cobalt-catalyzed ring-formation reactions as well as towards c...
