Synthesis of Trinitromethyl- and Dinitromethyl-Substituted Azoles Using Nitrate Salts in Sulfuric Acid [作者：THOTTEMPUDI VENUGOPAL; SHREEVE JEANNE M,期刊：Synthesis, 页码：1253-1257 , 文章类型： Article，,卷期：2012年44-8] Synthesis of trinitromethyl and dinitromethyl-substituted azoles employing a mild and efficient nitration method has been developed using a mixture of sulfuric acid and an inorganic nitrate salt XNO3, where X = NH4+, Na+... Molybdenum-Mediated Deconjugation of alpha,beta-Unsaturated Fused-Cyclopentenone Phosphonates [作者：MORADOV DORIT; RUBINSTEIN ABRAHAM; GELMAN DMITRI; SREBNIK MORRIS,期刊：Synthesis, 页码：1258-1262 , 文章类型： Article，,卷期：2012年44-8] The synthesis of diethyl (3-alkyl-5-oxo-4,5,6,6a-tetra-hydro-1H-cyclopenta[c]furan-4-yl)phosphonates from the corresponding 3-allyloxy-1-propynylphosphonates is described. The in situ reaction involves two steps: an intr... Easy Synthesis of Novel 4-Azolylpyridazin-3-ones [作者：GERASCHENKO OLEKSANDR V; KHODAKOVSKIY PAVEL V; SHIVANYUK OLEKSANDR N; SHISHKIN OLEG V; MYKHAILIUK PAVEL K; TOLMACHEV ANDREY A,期刊：Synthesis, 页码：1263-1267 , 文章类型： Article，,卷期：2012年44-8] Ethyl azol-2-ylglyoxylates react smoothly with acetone in the presence of catalytic amounts of proline and trifluoroacetic acid to give the corresponding azolyl aldols in 93-98% yield. The products are easily transformed... Synthesis of Cyclopentacarbazolones via Palladium-Catalyzed Annulation of Internal Alkynes [作者：SREENIVAS DEVANGA K; SANDHYARANI JATOTH; NAGARAJAN RAJAGOPAL,期刊：Synthesis, 页码：1268-1278 , 文章类型： Article，,卷期：2012年44-8] A simple and efficient protocol for the synthesis of highly substituted cyclopentacarbazolones (50-82%) was developed by employing internal alkynes with 2-bromo-3-formylcarbazoles in the presence of palladium catalyst un...
