标题 :Synthesis of haloindenes
发明人：WNUK STANISLAW F; HOWLADER MD ABU HASAN
权利人:WNUK STANISLAW F; HOWLADER MD ABU HASAN; THE FLORIDA INTERNATIONAL UNIV BOARD OF TRUSTEES
摘要:The subject invention provides an expedited synthesis of 5, 6, and 7-iodoindenes from the corresponding aminoindan-1-ones in more than 70% yield, employing readily available precursors and reagents. A three-step sequence involves diazotization-iodination of aminoindan-1-one followed by reduction and dehydration. The method has a general character and can be extended for the preparation of various 4-, 5-, 6- or 7-haloindenes using different halogen sources for diazotization-halogenation reaction.

标 题:Synthesis of bis-oxime heterocycles
发明人：BLUMBERG SHAWN T; DORSEY CHRISTOPHER L
权利人:SOUTHWEST RES INST
摘要:A synthesis of bis-oxime heterocycles via reaction of 2,4-dimethyl pyridine or 2,4-dimethylpyrimidine in the presence of a phase transfer catalyst. Such bis-oxime heterocycles provide a more direct route to the synthesis of bis-quaternary pyridinium compounds and their analogs as nerve agent antidotes.

标 题 :Synthesis of enantiomerically pure amino-substituted fused bicyclic rings
发明人：MCEACHERN ERNEST J; BRIDGER GARY J; SKUPINSKA KRYSTYNA A; SKERLJ RENATO T; YANG WEN
权利人:ANORMED INC
摘要:This invention describes various processes for synthesis and resolution of racemic amino-substituted fused bicyclic ring systems. One process utilizes selective hydrogenation of an amino-substituted fused bicyclic aromatic ring system. An alternative process prepares the racemic amino-substituted fused bicyclic ring system via nitrosation. In addition, the present invention describes the enzymatic resolution of a racemic mixture to produce the (R)- and (S)-forms of amino-substituted fused bicyclic rings as well as a racemization process to recycle the unpreferred enantioner. Further provided by this invention is an asymmetric synthesis of the (R)- or (S)-enantiomer of primary amino-substituted fused bicyclic ring systems.
