[作者：Dong, Cheng-Guo;Liu, Tao-Ping;Hu, Qiao-Sheng;,期刊：Synthesis, 页码：2650-2658 , 文章类型： 研究论文，,卷期：2008年-16] Palladium-catalyzed domino reactions of (E)-1,2-dibromoethenes with hindered Grignard reagents based on carbopalladation, palladium-catalyzed cross-coupling, and C-H activation are described. These domino reactions could... Chiral N-phosphonyl imine chemistry: asymmetric addition of ketone-derived enolates for the synthesis of b-amino ketones. [作者：Han, Jianlin;Ai, Teng;Li, Guigen;,期刊：Synthesis, 页码：2519-2526 , 文章类型： 研究论文，,卷期：2008年-16] New chiral N-phosphonyl imines were synthesized in good yields under convenient reaction conditions. These chiral N-phosphonyl imines can serve as efficient electrophiles for asym. addn. reactions with lithium ketone en... A new enantioselective catalytic route to Florhydral. [作者：Bovo, Sara;Scrivanti, Alberto;Bertoldini, Matteo;Beghetto, Valentina;Matteoli, Ugo;,期刊：Synthesis, 页码：2547-2550 , 文章类型： 研究论文，,卷期：2008年-16] The valuable fragrance Florhydral [3-(3-isopropylphenyl)butanal] was synthesized in almost enantiomerically pure form by a new catalytic route. The key step of the process is the enantioselective hydrogenation of (E)-3-... Ortho-selective cross-coupling of fluorobenzenes with Grignard reagents: acceleration by electron-donating ortho-directing groups. [作者：Manabe, Kei;Ishikawa, Shunpei;,期刊：Synthesis, 页码：2645-2649 , 文章类型： 研究论文，,卷期：2008年-16] Fluorobenzenes with directing groups, such as OH, CH2OH, and NH2, underwent ortho-selective cross-coupling with Grignard reagents in the presence of Pd-based catalysts, with dichlorobis(tricyclohexylphosphine)palladium [... Nickel-catalyzed cross-coupling reactions of alkyl aryl sulfides and alkenyl alkyl sulfides with alkyl Grignard reagents using (Z)-3,3-dimethyl-1,2-bis(diphenylphosphino)but-1-ene as ligand.
