专利号:US-7098342-B2 优先权日:2003-10-16 标题 :Preparation of candesartan cilexetil 发明人:ETINGER MARINA YU; FEDOTEV BORIS; DOLITZKY BEN-ZION 权利人:TEVA PHARMA 摘要:The invention encompasses processes for the synthesis of cilexetil trityl candesartan from the reaction of trityl candesartan with cilexetil halide in the presence of a base and a low boiling organic solvent. Optionally, the reaction may be conducted in the presence of a phase transfer catalyst.
专利号:US-2008214386-A1 优先权日:2004-03-01 标题:Catalyst for Cyclic Carbonate Synthesis 发明人:TAKAHASHI TOSHIKAZU; WATAHIKI TSUTOMU; YASUDA HIROYUKI; SAKAKURA TOSHIYASU 权利人:TAKAHASHI TOSHIKAZU; WATAHIKI TSUTOMU; YASUDA HIROYUKI; SAKAKURA TOSHIYASU 摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.
