Since some enzymes play crucial roles in bacterial resistance pathways, we here introduce the synthesis and application of small su... Ruthenium Lewis Acid Catalyzed Asymmetric 1,3-Dipolar Cycloadditions between N-Methylnitrones and Enals [作者：BADOIU ANDREI; BERNARDINELLI GERALD; KUENDIG E PETER,期刊：Synthesis, 页码：2207-2212 , 文章类型： Article，,卷期：2010年-13] N-Methylisoxazolidines are formed in good yields and high regio-, diastereo- and enantioselectivity via asymmetric 1,3-dipolar cycloaddition of nitrones with enals catalyzed by a chiral ruthenium Lewis acid. Electronic e... Classical Versus Nonstatistical Behavior in the C-2-C-6/Ene Cyclization of Enyne-Allenes: Intramolecular Kinetic Isotope Effects and Radical Clock Reactions [作者：VAVILALA CHANDRASEKHAR; BATS JAN W; SCHMITTEL MICHAEL,期刊：Synthesis, 页码：2213-2222 , 文章类型： Article，,卷期：2010年-13] The effects of aryl groups on the mechanism of the C-2-C-6/ene cyclization of enyne-allenes were studied by means of radical clock openings and intramolecular kinetic isotope effects. Upon attachment of a single aryl gro... Connecting C-19 Norditerpenoids to C-20 Diterpenes: Total Syntheses of 6-Hydroxy-5,6-dehydrosugiol, 6-Hydroxysugiol, and Taiwaniaquinone H, and Formal Synthesis of Dichroanone [作者：JANA CHANDAN KUMAR; SCOPELLITI ROSARIO; GADEMANN KARL,期刊：Synthesis, 页码：2223-2232 , 文章类型： Article，,卷期：2010年-13] Oxidation of the B-ring of abietane derivatives by Sharpless dihydroxylation gave the natural products 6-hydroxy-5,6-dehydrosugiol and 6-hydroxysugiol. Moreover, further oxidation gave a hydroxy dione derivative that pro... On the Development of Catalytic Carba-6 pi Electrocyclizations [作者：BISHOP LEE M; ROBERSON RUSSELL E; BERGMAN ROBERT G; TRAUNER DIRK,期刊：Synthesis, 页码：2233-2244 , 文章类型： Article，,卷期：2010年-13] Hexatriene substrates substituted in the 2-position with carbonyl groups were studied in the context of catalytic 6 pi electrocyclizations. The nature of the carbonyl group and the substitution pattern on the hexatriene ... Ruthenium-Catalyzed C-H Bond Functionalizations of 1,2,3-Triazol-4-yl-Substituted Arenes: Dehydrogenative Couplings Versus Direct Arylations [作者：ACKERMANN LUTZ; NOVAK PETR; VICENTE RUBEN; PIROVANO VALENTINA; POTUKUCHI HARISH K,期刊：Synthesis, 页码：2245-2253 , 文章类型： Article，,卷期：2010年-13] The chemoselectivity of ruthenium-catalyzed C-H bond arylations on triazol-4-yl-substituted arenes was found to depend on the substitution pattern of both substrates. While various aryl chlorides led to products stemming... Multidimensional Screening and Methodology Development for Condensations Involving Complex 1,2-Diketones [作者：GOODELL JOHN R; LENG BO; SNYDER TRACY K; BEELER AARON B; PORCO JOHN A JR,期刊：Synthesis, 页码：2254-2270 , 文章类型： Article，,卷期：2010年-13] Multidimensional reaction screening with complex cycloheptane-1,2-diones is described. The studies resulted in the discovery of regioselective Lewis acid mediated condensation reactions with substituted ureas, and a dias... Asymmetric Synthesis of Thiadecalins via an Organocatalytic Triple Cascade/Sulfa-Michael Sequence [作者：ENDERS DIETER; SCHMID BERTRAM; ERDMANN NICO; RAABE GERHARD,期刊：Synthesis, 页码：2271-2277 , 文章类型： Article，,卷期：2010年-13] An efficient two-step asymmetric synthesis of highly substituted cis-configured thiadecalins and the corresponding hexahydrobenzothiophene core is described. Thiadecalin derivatives are known for their widespread biologi... Preparation and N-Alkylation of 4-Aryl-1,2,4-triazoles [作者：HOLM STEFANIE C; SIEGLE ALEXANDER F; LOOS CHRISTIAN; ROMINGER FRANK; STRAUB BERND F,期刊：Synthesis, 页码：2278-2286 , 文章类型： Article，,卷期：2010年-13] Heating of N,N-dimethylformamide azine dihydrochloride {N'-[(dimethylamino)methylene]-N,N-dimethylhydrazonoformamide dihydrochloride} with anilines in the absence of a solvent gave a range of 4-aryl-1,2,4-triazoles by di... Synthesis of Schaefferals A and B, Unusual Phenylhydrazine Derivatives from Mushrooms of the Genus Agaricus [作者：KILECIKSOLL RENGIN; WINKLHOFER CHRISTIAN; STEGLICH WOLFGANG,期刊：Synthesis, 页码：2287-2291 , 文章类型： Article，,卷期：2010年-13] Schaefferals were identified as chromogens responsible for the development of an orange to red color after treating the caps of certain Agaricus species with aniline and nitric acid (Schaeffer's cross reaction). The stru... Efficient Access to Aminomannoside Derivatives via Formal [2+2] Cycloaddition of Triazolinediones and Tri-O-acetyl-D-glucal [作者：DAHL RUSSELL; BALDRIDGE KIM K; FINNEY NATHANIEL S,期刊：Synthesis, 页码：2292-2296 , 文章类型： Article，,卷期：2010年-13] Triazolinediones react with tri-O-acetyl-D-glucal to provide the corresponding diazetidines as single stereoisomers possessing the mannosamine configuration at C2.
