[作者：Alizadeh, Abdolali;Rostamnia, Sadegh;Zhu, Long-Guan;,期刊：Synthesis, 页码：1788-1792 , 文章类型： 研究论文，,卷期：2008年-11] We recently reported a new class of PPh3- and isocyanide-based multicomponent reactions (Ph3P/DAAD and IMCRs/DAAD) mediated by R3P/DAAD and RNC/DAAD zwitterionic intermediates in the presence of CH, OH, and NH acids. He... Copper-mediated 3-N-arylation of flavins. [作者：Attenberger, Bianca;Schmaderer, Harald;Koenig, Burkhard;,期刊：Synthesis, 页码：1767-1774 , 文章类型： 研究论文，,卷期：2008年-11] A generally applicable method for the direct 3-N-arylation of flavins using arylboronates and Cu(OAc)2 was developed. The reaction conditions were optimized considering the lability of flavins in basic conditions and th... A stereospecific route to (Z)-urocanic acids. [作者：Despinoy, Xavier L. M.;McNab, Hamish;Tyas, Richard G.;,期刊：Synthesis, 页码：1676-1678 , 文章类型： 研究论文，,卷期：2008年-11] (Z)-Urocanic acid (I) and its derivs. can be made stereospecifically by ring-opening of pyrrolo[1,2-c]imidazol-5-ones II [R1 = R2 = H; R1 = Me, R2 = H, Ph] in aq. THF. Rapid and convenient microwave-assisted synthesis of primary amines via reductive N-alkylation of methyl carbamate with aldehydes. [作者：Lehmann, Fredrik;Scobie, Martin;,期刊：Synthesis, 页码：1679-1681 , 文章类型： 研究论文，,卷期：2008年-11] Microwave-assisted reductive alkylation of Me carbamate with a range of aldehydes provides, after basic work-up, an exptl. simple, one-pot method for rapid functional group interconversion of structurally diverse aldehyd... Recent progress in the catalytic synthesis of tertiary alcohols from ketones with organometallic reagents. [作者：Hatano, Manabu;Ishihara, Kazuaki;,期刊：Synthesis, 页码：1647-1675 , 文章类型： 综述，,卷期：2008年-11] A review. Efficient tertiary alc. synthesis is currently one of the most rapidly advancing fields in org. chem., and recent powerful catalytic methodologies can provide versatile tertiary alcs., even with enantioselecti... Efficient synthesis of monosubstituted 3-alkynylfurans via Suzuki coupling. [作者：Yang, Xiaobao;Zhu, Li;Zhou, Yuedong;Li, Zhong;Zhai, Hongbin;,期刊：Synthesis, 页码：1729-1732 , 文章类型： 研究论文，,卷期：2008年-11] A convenient synthesis of monosubstituted 3-alkynylfurans by Suzuki coupling reaction of 3-furanyl-boronic acid with substituted acetylene bromides was described. The internal alkyne products were attainable in 50-89% y... H2O2/Tf2O system. An efficient oxidizing reagent for selective oxidation of sulfanes. [作者：Khodaei, Mohammad Mehdi;Bahrami, Kiumars;Karimi, Ahmad;,期刊：Synthesis, 页码：1682-1684 , 文章类型： 研究论文，,卷期：2008年-11] A versatile procedure for the oxidn. of sulfides to sulfoxides without any over-oxidn. to sulfones was reported. It is noteworthy that the reaction tolerates oxidatively sensitive functional groups and that the sulfur a... Stereoselective synthesis of b-C-allyl- and b-C-propargyl-D-arabinofuranosides. [作者：Ramana, C. V.;Narute, Sachin B.;Gonnade, Rajesh G.;Patil, Rahul S.;,期刊：Synthesis, 页码：1783-1787 , 文章类型： 研究论文，,卷期：2008年-11] The stereoselective synthesis of b-configured C-allyl- and C-propargyl-D-arabinofuranosides (4,7-anhydro-1,2,3-deoxy-D-gluco-oct-1-enitols and -oct-1-ynitols) was addressed by employing allylation/propargylation of a dia... A new strategy for the synthesis of (?-lupinine and (?-epilupinine via cyclization of a-sulfinyl carbanions. [作者：Pohmakotr, Manat;Seubsai, Anusorn;Numeechai, Pornthep;Tuchinda, Patoomratana;,期刊：Synthesis, 页码：1733-1736 , 文章类型： 研究论文，,卷期：2008年-11] (?-Lupinine (I) and (?-epilupinine were prepd. starting from com. available d-valerolactam (II). The synthetic route involves the advantages of the cyclization based on a-sulfinyl carbanions.
