[作者：Muzalevskiy, Vasiliy M.;Nenajdenko, Valentine G.;Shastin, Aleksey V.;Balenkova, Elizabeth S.;Haufe, Gunter;,期刊：Synthesis, 页码：2899-2904 , 文章类型： 研究论文，,卷期：2008年-18] 1-(3-Bromo-3,3-difluoroprop-1-ynyl)benzenes are good dienophiles in Diels-Alder reactions. Based on this key reaction, a new pathway towards biaryls with an ortho-CF2Br group was elaborated. An easy and efficient one-step procedure for the preparation of alkyl and aryl alkylcarbamates from S-methyl N-alkylthiocarbamates. [作者：Degani, Iacopo;Fochi, Rita;Magistris, Claudio;,期刊：Synthesis, 页码：2919-2924 , 文章类型： 研究论文，,卷期：2008年-18] A general, 1-step procedure for the synthesis of alkyl and aryl alkylcarbamates, by the direct reaction of S-Me N-alkylthiocarbamates with alcs. or phenols in toluene at reflux in the presence of Et3N, is reported. All ... trans-resveratrol-d4, a molecular tracer of the wild-type phytoalexin; synthesis and spectroscopic properties. [作者：Gabriele, Bartolo;Benabdelkamel, Hicham;Plastina, Pierluigi;Fazio, Alessia;Sindona, Giovanni;Di Donna, Leonardo;,期刊：Synthesis, 页码：2953-2956 , 文章类型： 研究论文，,卷期：2008年-18] A 6-step synthesis of trans-resveratrol-d4, (E)-3',4,5'-trihydroxy-2,3,5,6-tetradeuterostilbene, starting from com. available phenol-d6, with overall yield of 25%, is described. The reaction involves phenol-d6 methylati... Chiral confined space: induction of stereochemistry in a M4L4 metallosupramolecular container.

[Ti4L4]8- tetrahedra as al... Copper(I)-catalyzed three-component coupling leading to an efficient synthesis of b,g-alkynyl a-amino acid derivatives. [作者：Shao, Zhihui;Chan, Albert S. C.;,期刊：Synthesis, 页码：2868-2870 , 文章类型： 研究论文，,卷期：2008年-18] The first copper(I)-catalyzed direct three-component coupling of Et glyoxylate, p-anisidine, and terminal alkynes has been developed. This protocol provides an efficient method to prep. b,g-alkynyl a-amino acid derivs. ... Comprehensive experimental and theoretical studies of configurationally labile epimeric diamine complexes of a-lithiated benzyl carbamates. [作者：Lange, Heiko;Huenerbein, Robert;Wibbeling, Birgit;Froehlich, Roland;Grimme, Stefan;Hoppe, Dieter;,期刊：Synthesis, 页码：2905-2918 , 文章类型： 研究论文，,卷期：2008年-18] Different primary benzyl-type carbamates were deprotonated by sec-butyllithium in the presence of a tert-leucinol-derived bis(oxazoline) ligand. The resulting configurationally labile epimeric complexes equilibrated and... Chiral bispidines.
