This protocol significantly reduces the cost and time for the s... 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... Reaction of Dichloronaphthazarins with Sodium Nitrite as a Route to Natural Pigments Echinamines A and B and Related Aminonaphthazarins [作者：POLONIK NIKITA S; POLONIK SERGEY G; DENISENKO VLADIMIR A; MOISEENKO OLGA P,期刊：Synthesis, 页码：3350-3358 , 文章类型： Article，,卷期：2011年-20] A series of 6,7-disubstituted 2-hydroxy-3-nitronaphthazarins were prepared by treatment of 2,3-dichloronaphthazarins with sodium nitrite. Acid-catalyzed hydrolysis of a mixture of two isomeric 6(7)-ethoxy-7(6)-ethyl-subs...
