Intermediates in the synthesis of macrolides including the eastern and western halves are also provided. Pharmaceutical compositions and methods of treating infectious diseases and inflammatory conditions using the inventive macrolides are also provided. A general diastereoselective aldol methodology used in the synthesis of the western half is further provided.
专利号:US-6407299-B1 优先权日:1999-06-02 标 题:Alkyl magnesium catalyzed synthesis of ethylene and α-olefin polymers 发明人:SEN AYUSMAN; KIM JANG SUB 权利人:EXXONMOBIL RES & ENG CO; PENNSYLVANIA STATE RES FOUNDAT 摘要:The present invention is a two-component catalyst system comprising (a) an alkyl magnesium (MgR 2 ) component and (b) a Lewis acid component. The catalyst system is used for catalyzing the oligomerization and polymerization of ethylene and/or α-olefins to form homopolymers and copolymers. The products range from highly linear, high molecular weight, solid polymers to highly branched, lower molecular weight oils.
