These derivatives are inhibitors of SRS-A synthesis and are useful for treating and preventing allergic reactions.
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.

参考标题:Total Synthesis Of Leopolic Acid A, A Natural 2,3-Pyrrolidinedione With Antimicrobial Activity 作者:Atul A Dhavan,Rahul D Kaduskar,Loana Musso,Leonardo Scaglioni,Piera Anna Martino,Sabrina Dallavalle 摘要:The First Total Synthesis Of Leopolic Acid A, A Fungal Metabolite With A Rare 2,3-Pyrrolidinedione Nucleus Linked To An Ureido Dipeptide, Was Designed And Carried Out. Crucial Steps For The Strategy Include A Dieckmann Cyclization To Obtain The 2,3-Pyrrolidinedione Ring And A Wittig Olefination To Install The Polymethylene Chain. An Oxazolidinone-Containing Leopolic Acid A Analogue Was Also Synthesized
