- Synthesis of 4,4-Disubstituted Piperidine-2-carbonitriles and Piperidine-2,6-dicarbonitriles as Precursors for New alpha-Amino Acids
[作者:SCHMAUNZ CORNELIA E; WANNER KLAUS T,期刊:Synthesis, 页码:3332-3342 , 文章类型: Article,,卷期:2011年-20]
- An easy and straightforward method for the synthesis of 4,4-disubstituted pipecolic acid and piperidine-2,6-dicarboxylic acid derivatives has been developed, based on the addition of cyanide ions to 4,4-disubstituted 1,4...
- Stereoselective Total Synthesis of Achaetolide from L-Malic Acid
[作者:SABITHA GOWRAVARAM; SRINIVAS RANGAVAJJULA; YADAV JHILLU S,期刊:Synthesis, 页码:3343-3349 , 文章类型: Article,,卷期:2011年-20]
- A convergent total synthesis of achaetolide is described. The key steps include a Horner-Wadsworth-Emmons olefination, CBS reduction to install the stereochemistry at the C9 center, stereoselective vinylation to introduc...
- A Versatile Route to N,N '-Tetraaryl-Substituted 2,5-Diaminothiophenes
[作者:HEICHERT CHRISTOPH; WRACKMEYER MARION; HARTMANN HORST,期刊:Synthesis, 页码:3375-3378 , 文章类型: Article,,卷期:2011年-20]
- By reaction of N,N'-tetraaryl-substituted succinic diamides with Lawesson's reagent, a series of N,N'-tetraaryl-substituted 2,5-diaminothiophenes was prepared. The N,N'-tetrakis(4-bromophenyl)- 2,5-diaminothiophene, thus...
