摘要:8 个 α,β-不饱和羰基化合物 1-(2'-或 4'-取代苯基)-3-苯基-2-丙烯-1-酮 (2'-或 4'-取代查耳酮),在硅胶存在下在苯中通过 Nad(P)H 模型还原.所有这些都定量地提供了相应的饱和羰基化合物,而没有发生 1,2-还原.对于 2'-甲氧基,4'-甲基,4'-溴和 4'-硝基衍生物以及未取代的羰基化合物,底物的表观反应活性随着取代基吸电子能力的增加而增加,而硅胶表面的吸附量减少.同样明显的是,尽管 4'-羟基衍生物的吸附效率更高,但 4'-羟基衍生物的反应活性低于 2'-羟基衍生物.

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.

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.

权利人:OREAL
摘要:A method for managing skin tone comprising reducing the synthesis of melanin by applying a skin treatment composition to skin. The skin treatment composition may include about 0.1 to about 25 wt. % of acetyl trifluoromethylphenyl valylglycine; about 0.5 to about 30 wt. % of a polyol; about 0.1 to about 30 wt. % of a silicone, fatty compound, or a mixtures thereof, wherein the skin treatment composition is an emulsion, and all weight percentages are based on the total weight of the skin treatment composition.
