标题:Pd / Tio 2 + Fecl 3串联催化剂促进芳族酮和醛的室温化学选择性脱氧
摘要:描述了一种快速实用的各种芳族酮和醛化学选择性脱氧的方案,该方案使用了由多相pd / Tio 2 +均相fecl 3与绿色氢源,聚甲基氢硅氧烷(pmhs)组成的串联催化剂.所开发的催化系统坚固耐用且可扩展,例如苯乙酮的脱氧反应,该反应在大气环境中以克为单位进行,仅使用0.4 Mol%pd / Tio 2 + 10 Mol%fecl 3催化剂在相应的乙苯中制得.在室温下10分钟内产率为96%.此外,Pd / Tio 2催化剂可循环使用多达三遍,效率未见明显下降,并且在反应条件下其金属浸出率低.通过操作红外,核磁共振和gc-Ms技术研究了钯催化芳族酮和醛的还原性脱氧反应机理.

标题:Process for stereoselective synthesis of prostacyclin derivatives
发明人：MORIARTY ROBERT M; PENMASTA RAJU; GUO LIANG; RAO MUNAGALA S; STASZEWSKI JAMES P
权利人:UNITED THERAPEUTIC CORP
摘要:An improved method is described for making 9-deoxy-PGF 1 -type compounds. In contrast to the prior art, the method is stereoselective and requires fewer steps than the known methods for making these compounds. The invention also relates to novel intermediates prepared during the synthesis of the 9-deoxy-PGF 1 -type compounds.

标题 :Means and methods for synthesizing precursors of y-aminobutyric acid (gaba) analogs
发明人：POELARENDS GERRIT JAN; BIEWENGA LIEUWE; VAN DER MEER JAN-YTZEN; PODDAR HARSHWARDHAN; THANGAVELU SARAVANAN
权利人:UNIV GRONINGEN
摘要:The invention relates to the fields of drug development and biocatalysis, more specifically to a biocatalytic route for asymmetric synthesis of precursors of y-aminobutyric acid (GABA) analogs. Provided is an isolated mutant 4-oxalocrototonate tautomerase (4-OT) enzyme comprising the following mutations (i) leucine at position 8 substituted with a tyrosine (L8Y) or a phenylalanine (L8F); (ii) methionine at position 45 substituted with a tyrosine (M45Y); and (iii) phenylalanine at position 50 substituted with an alanine (F50A), wherein the positions are numbered according to the amino acid sequence of 4-OT ofPseudomonas putida.Also provided is a method for the synthesis of a precursor for the pharmaceutically relevant enantiomer of a GABA analog, comprising (i) providing a y-nitroaldehyde using the 4-OT mutant enzyme, followed by (ii) subjecting the thus obtained y-nitroaldehyde to an enzymatic oxidation reaction catalyzed by an aldehyde dehydrogenase (EC 1.2.1.3).
