摘要:两种具有[re(co)3(l)br]的溴mo(i)羰基配合物,其中l = 1,10-菲咯啉(phen-Re)和5-(1H-吡咯-1-基)-1,10-菲咯啉(pyph-再),成功地与分析吡咯(该效果的目的合成py上的光物理性质)部分pyph-再.发现phen-Re和pyph-Re的三重态金属到配体的电荷转移dπ(re)->π*(n-N)发射居中于.527 Nm,发光量子产率(lqy)为0.015,大约 578 Nm,Lqy分别为0.011.同时,还使用在c,H,N,O和br原子上使用的6-31G *基集计算了基态的几何结构和phen-Re和pyph-Re的吸收光谱性质,在re原子上采用了lanl2Dz.根据实验和理论分析,光致发光光谱的红移和pyph-Re的lqy较低应主要归因于最高占据分子轨道与最低未占据分子轨道之间的能隙变窄以及llct跃迁更多定量pyph

摘要:Disclosed herein is an improved and efficient process for synthesis of vitamin D3 and its analogue Calcifediol from Ergosterol. Particularly, the present invention discloses the synthesis of key intermediate 3β-tert-Butyldimethylsilyloxy-22-hydroxy-23,24-bisnorchola-5,7-diene (5), and novel intermediate β-tert-Butyldimethylsilyloxy-22-iodo-23,24-bisnorchola-5,7-diene (9) by a simple and cost effective process. The industrially viable processes for preparation of said intermediate(s) results in providing provitamins with various side chains and the desired products in high yield.

摘要:The present invention relates to a process for the regioselective synthesis of compounds of the formula I, wherein R1; R2; R3; R4; J1; J2; J3; J4 and G have the meanings indicated in the claims. The present invention provides a direct metal, e.g. palladium or copper, catalyzed, regioselective process to a wide variety of unsymmetrical, multifunctional N-substituted benzimidazoles or azabenzimidazoles of formula I starting from 2-halo-nitroarenes and N-substituted amides.

标 题 :Synthesis of 25-hydroxy-vitamin d3, 25-hydroxy-7-dehydrocholesterol and analogous alcohols using the beta-proteobacterium thauera aromatica
发明人：BOLL MATTHIAS; JACOBY CHRISTIAN
权利人:UNIV FREIBURG ALBERT LUDWIGS
摘要:The present invention relates to methods using recombinant Thauera aromatica cells to produce oxygen-independent molybdenum-hydroxylases in order to convert vitamin D 3 , 7-dehydrocholesterol and related alkylated compounds into 25-hydroxy-vitamin D 3 , 25- hydroxy-7-dehydrocholesterol and analogous alcohols. The underlying biocatalytic method links the water-dependent hydroxylation of alkyl residues with the nitrate- reducing respiratory chain of the strain as electron acceptor system. In contrast to commonly used methods, the present method does no longer require the artificial regeneration of the electron-carrier.
