标 题 :Process for the preparation of 2,7-dihydroxy-9-fluorenone useful for the synthesis of tilorone and its salts

摘要:Methods involving preparation of building blocks of 2,7-dihydroxy-9-fluorenone toward the synthesis of tilorone dihydrochloride salt and other salts (bromide, iodide, fluoride, citrate, oxalate, maleate, phosphate, tartrate, triflate, trifluoroacetate, tetrafluoroborate) of tilorone, and an efficient, safe, cost effective method for the preparation of 2,7-bis-[2-(diethylamino)ethoxy]-fluorenone-9 and its various salts are developed. The methods involve oxygenation of fluorene, nitration of fluorenone, followed by reduction and diazotization toward the formation of 2,7-dihydroxy-9-fluorenone, which is the key intermediate for the formation of 2,7-bis-[2-(diethylamino)ethoxy]-9-fluorenone-dihydrochloride (Tilorone dihydrochloride) and other tilorone salts. The synthesis method has relatively simple operation, mild reaction conditions, high yield, and simple process with yields of 80-97%. Subsequent product purification of this method uses filtration and crystallization methods, avoiding the existing methods of column chromatography. Therefore, the research of its synthetic method being with a wide range of applications from the drug development and material synthesis point of view.

标题 :Method for the synthesis of nanoparticles of heterometallic nanocomposite materials

摘要:A simple one pot sol-gel method for the synthesis of bi-metal nanostructures is based on non-noble metals (Fe, Co and Sn) and titanium. The method involves the synthesis of mixed metal nanoscale composites using low cost precursors which allow for the synthesis of desired nanocomposite materials with self-scarifying titanium or silica supports. The procedure does not require any surfactant or any need for pH controlled step. Applicants' method involves the in-situ generation of precursors and their simultaneous entrapment in a gel. This simple one pot synthesis allows for the synthesis of homogenous size, shape and distribution of targeted nanostructures. Further, this method can be applied for the preparation of various nanocomposite materials using different choices of metals and self-scarifying supports. Applicants also show that Pd, the noble metal based nanocomposite is feasible.

标 题 :Stereoselective synthesis of selective estrogen receptor down-regulators
权利人:BAYER SCHERING PHARMA AG; ASTRAZENECA AB
摘要:The present invention relates to stereoselective synthesis of 7-α-substituted estra-4-ene-3,17-diones. Such compounds are valuable intermediates in the synthesis of 7-α-substituted estra-1,3,5(10)-triene-3,17-diols. n Key step in this synthesis is reacting a 3-keto-4,6-estradiene with a Grignard reagent selected from the group consisting of a magnesium-halide alkyl halide having at least 3 carbon atoms, a magnesium-halide alkenyl halide having at least 3 carbon atoms, and a magnesium-halide alkynyl halide having at least 3 carbon atoms, in the presence of a catalyst system comprising CuI. n The obtained 7α-alkyl, alkenyl and alkynyl halides can be used for the synthesis of pharmaceutically actice 7-α-substituted estra-1,3,5(10)-triene-3,17-diols (antiestrogens).
