专利号:US-9982005-B2 优先权日:2013-04-04 标 题 :Macrolides and methods of their preparation and use 发明人:MYERS ANDREW G; SEIPLE IAN BASS; ZHANG ZIYANG 权利人:HARVARD COLLEGE 摘要:Provided herein are methods of preparing macrolides by the coupling of an eastern and western half, followed by macrocyclization, to provide macrolides, including both known and novel macrolides. 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-7470792-B2 优先权日:2002-09-13 标题:Process for the preparation of epothilone derivatives, new epothilone derivatives as well as new intermediate products for the process and the methods of preparing same 发明人:KOCH GUIDO; LOISELEUR OLIVIER 权利人:NOVARTIS AG 摘要:The present invention provides a synthesis for the preparation of epothilone derivatives of formula 9 n nwherein R1 is methyl, and R2 is an unsubstituted or substituted aryl; an unsubstituted or substituted heteroaryl; or an unsubstituted or substituted heterocyclic radical fused to a benzene nucleus; and salts thereof, and intermediates for the synthesis of a compound of formula 9.
专利号:US-3943142-A 优先权日:1969-01-24 标 题:Dye intermediates and their preparation and use in the synthesis of methine dyes 发明人:OWEN JOHN R 权利人:EASTMAN KODAK CO 摘要:Compositions of matter are provided comprising a stable, non-vaporous monomeric methylene base selected from a 2-methylenethiazoline; a 2-methylenebenzothiazoline; a 2-methylenenaphthothiazoline; a 2-methylenebenzoselenazoline; and a 2-methylenenaphthoselenazoline. The compositions of the invention are prepared by reacting the parent 2-methyl quaternary salt with a non-hydroxylic base which removes a proton of the heterocyclic salt together with a proton acceptor which inhibits build-up of the hydro salt of the non-hydroxylic base, the reaction being conducted under anhydrous conditions in a non-hydroxylic liquid in which the heterocyclic quaternary salt is sufficiently insoluble to inhibit dimer formation. The compositions of the invention are employed in the preparation of methine dyes.
