标题:通过可伸缩,环保且经济高效的工艺机械合成磺酰胺
摘要:在此,我们展示了一种无溶剂机械化学方法,涉及由固体次氯酸钠(naocl.5H 2 O)介导的一锅双步程序,用于合成磺酰胺.该方案需要在催化固体酸性物质存在下对二硫化物进行串联氧化氯化反应,然后在路易斯酸碱固体无机试剂的促进下进行胺化.该方法适用于芳香族和脂肪族二硫化物和胺.纯化过程充分考虑了环境问题,避免了恶劣的条件,以获得纯净的磺酰胺产品.一些相关的生物活性化合物已经用此过程制备.

标题:Process for the synthesis of vinyl sulfenic acid derivatives
发明人：HOARD DAVID W; LUKE WAYNE D
权利人:LILLY CO ELI
摘要:The present invention is directed to a new process for the synthesis of vinyl sulfenic acid derivatives. These compounds are useful for the synthesis of benzo[b]thiophenes, in particular 2-aryl-benzo[b]thiophenes.

标 题 :Synthesis of [2.2.1]bicyclo nucleosides
发明人：KOCHKINE ALEXEI; FENSHOLDT JEF; PFUNDHELLER HENRIK M
权利人:EXIQON AS
摘要:A synthesis of [2.2.1]bicyclo nucleosides which is shorter and provides higher overall yields proceeds via the key intermediate of the general formula III, wherein R4 and R5 are, for instance, sulfonates and R7 is, for instance, a halogen or an acetate. From compounds of the general formula II, such as 3-O-aryl-4-C-hydroxymethyl-1,2-O-isopropylidene-alpha-D-ribofuranose, intermediates of the general formula III are suitable for coupling with silylated nucleobases. Upon one-pot base-induced ring-closure and desulfonation of the formed [2.2.1]bicyclo nucleoside, a short route to each the LNA (Locked Nucleic Acid) derivatives of adenosine, cytosine, uridine, thymidine and guanidine is demonstrated. The use of the 5'-sulfonated ring-closed intermediate also allows for synthesis of 5'-amino- and thio-LNAs.
