This tandem reaction involve... Synthesis of Novel Furo-, Thieno-, and Pyrroloazepines [作者：VILLARREAL CARLOS; MARTINEZ ROBERTO,期刊：Synthesis, 页码：3346-3352 , 文章类型： Article，,卷期：2010年-19] The synthesis of novel furo-, thieno-, and pyrroloazepine compounds, using the oxidative radical alkylation of three five-membered heterocyclic 3-acetic acid derivatives, is described. The bicyclic systems were obtained,... Synthesis of Enantiopure Quaternary Prolines by a Metathesis Process of 2,5-Ethenoproline Derivatives [作者：CARRERAS JAVIER; AVENOZA ALBERTO; BUSTO JESUS H; PEREGRINA JESUS M,期刊：Synthesis, 页码：3353-3357 , 文章类型： Article，,卷期：2010年-19] A novel azabicyclic amino acid was synthesized in both enantiopure forms. The ring-opening metathesis of methyl N-(tert-butoxycarbonyl)-7-azabicyclo[2.2.1]hept-2-ene-1-carboxylates was used as a method for accessing a ne... 1-Acylsemicarbazides by Ring Opening of Iminodiaziridines with Carboxylic Acids: Novel, Expeditious Access to the Azapeptide Motif [作者：QUAST HELMUT; SCHMITT EDELTRAUD; ROSS KARLHEINZ,期刊：Synthesis, 页码：3358-3362 , 文章类型： Article，,卷期：2010年-19] Carboxylic acids react rapidly and quantitatively with iminodiaziridines to afford 1,2,4-trisubstituted 1-acylsemicarbazides in a multistep sequence. In this way, a carboxy group is readily converted into an azapeptide m... Synthesis of 1,5,6,7-Tetrahydro-4H-pyrazolo[4,3-c]pyridin-4-ones as Conformationally Constrained Pyrazole Analogues of Histamine [作者：ZEROVNIK DARJA; GROSELJ UROS; KRALJ DAVID; MALAVASIC CRT; BEZENSEK JURE; DAHMANN GEORG; STARE KATARINA; MEDEN ANTON; STANOVNIK BRANKO; SVETE JURIJ,期刊：Synthesis, 页码：3363-3373 , 文章类型： Article，,卷期：2010年-19] Three synthetic methods for the preparation of 1,5-disubstituted 1,5,6,7-tetrahydro-4H-pyrazolo[4,3-c]pyridin-4-ones as heterocyclic histamine analogues were developed. The first method starts from easily available methy... Synthesis of Annulated Pyrroles: Condensation of Aldose Sugars, Arylamines, and 1,3-Diones Using TBAB [作者：NAGARAPU LINGAIAH; CHEEMALAPATI VENKATA NARASIMHAJI; KARNAKANTI SHUKLACHARY; BANTU RAJASHAKER,期刊：Synthesis, 页码：3374-3378 , 文章类型： Article，,卷期：2010年-19] Readily available tetrabutylammonium bromide (TBAB, 10 mol%), in the molten state, efficiently catalyzes the reaction of a variety of in situ generated enamines, from arylamines and 1,3-ketones, with aldose sugars under ... Synthesis of alpha-Aminocyclopropylphosphonic Acids [作者：CHEMAGIN ANDREY V; YASHIN NIKOLAI V; GRISHIN YURI K; KUZNETSOVA TAMARA S; ZEFIROV NIKOLAI S,期刊：Synthesis, 页码：3379-3383 , 文章类型： Article，,卷期：2010年-19] A convenient, general approach to alpha-aminocyclopropylphosphonic acids via reduction and hydrolysis of alpha-nitrocyclopropylphosphonates is described. A number of the title compounds were synthesized in excellent yiel... Reactions of Substituted Oxazoles and Thiazoles with Acid Chlorides: Carbon-Carbon Bond Formation through Cyclic Ketene Acetals [作者：CHATTERJEE SABORNIE; YE GUOZHONG; SONG YINGQUAN; BARKER BOBBY LLOYD; PITTMAN CHARLES U JR,期刊：Synthesis, 页码：3384-3394 , 文章类型： Article，,卷期：2010年-19] Reactions of 2,4,5-trimethyloxazole, 2,4,5-trimethylthiazole, 2-methylthiazole, and 2-ethyl-4,5-dimethylthiazole with different acid chlorides in the presence of different bases were explored. Arylvinyl esters of substit... Recent Advances in the Synthesis of Carbohydrate Mimetics [作者：KOESTER DENNIS C; HOLKENBRINK ANNIKA; WERZ DANIEL B,期刊：Synthesis, 页码：3217-3242 , 文章类型： Review，,卷期：2010年-19] Highly diverse strategies are employed to mimic carbohydrates. Two subgroups of carbohydrate mimetics are very important: alterations of the core structure and modifications of the O-glycosidic linkage. This review prese...
