标题:区域选择性铁催化脱羧烯丙基醚化
摘要:阴离子铁络合物以高收率催化酚类的脱羧烯丙基化反应,形成烯丙基醚.烯丙基化是区域选择性的而不是区域特异性的.这表明烯丙基化是通过π-烯丙基铁中间体进行的,与碳亲核试剂的相关烯丙基化相反,后者已提议通过σ-烯丙基络合物进行.最终,铁催化剂具有取代通常用于脱羧偶联的更昂贵的钯催化剂的潜力.

标题:Method of regioselective synthesis of substituted benzoates
发明人：KRAUS GEORGE A
权利人:KRAUS GEORGE A; UNIV IOWA STATE RES FOUND INC
摘要:A method of synthesis of para-substituted benzoate esters and acids is provided, wherein the para-substituted regioisomer is obtained substantially free of the meta-substituted impurity, the method comprising contacting a coumalate ester or acid and an unactivated alkene at elevated temperature in the presence of a metal oxidation catalyst and an oxidant. The metal oxidation catalyst can be palladium, such as palladium on carbon, and the oxidant can be the oxygen gas in ambient air. The reaction can be carried out without solvent or in high boiling hydrocarbon solvents such as mesitylene. When the unactivated alkene is a monosubstituted alkene, yields of at least about 50 or 60% of para-substituted ester and acid products, respectively, are obtained, substantially free of the regioisomeric meta-substituted impurity.

标题:Poly-diisopropenyl benzene synthesis
发明人：JALICS GEORGE
权利人:GOODYEAR TIRE & RUBBER
摘要:It has been unexpectedly found that meta-diisopropenyl benzene can be polymerized into poly-m-diisopropenyl benzene with a relatively narrow molecular weight distribution and with only a small degree of crosslinking (gel formation) if done in the presence of at least one alpha-olefin containing from 2 to 12 carbon atoms in tetrahydrofuran (solvent) at low temperatures employing an alkyl lithium initiator. The poly-m-diisopropenyl benzene produced by employing this technique has an isopropenyl moiety on almost every diisopropenyl benzene repeat unit in the polymer. This polymer is particularly useful since its pendant isopropenyl groups can be further reacted with other compounds leading to polymers with various functionalities. This technique can also be employed in the synthesis of copolymers containing repeat units derived from meta-diisopropenyl benzene and one or more other monomers. The copolymers synthesized using the process of this invention contain an essentially quantitative number of unreacted isopropenyl groups on the meta-disisopropenyl benzene repeat units in the polymer chain.

摘要:The present invention relates to a method for the synthesis of 4-demethoxydaunorubicin (idarubicin) having the chemical structure of formula (I), which involves the demethylation of 3′-Prot-daunorubicin in the presence of a soft Lewis acid. The method of the present invention does not comprise cleavage of the glycosidic linkage at carbon C7, thus resulting in a faster synthesis cycle and an improved yield of the final product.
