标 题 :Regiospecific synthesis of rapamycin 42-ester derivatives
发明人：GU JIANXIN; CAI PING; RUPPEN MARK E
权利人:WYETH CORP
摘要:A method for the regiospecific synthesis of rapamycin 42-ester derivatives is described. The method involves lipase-catalyzed acetylation of 42-hydroxy of rapamycin with an acyl donor such as a vinyl ester, an isopropenyl ester or an anhydride in a suitable organic solvent.

权利人:UNIV CARNEGIE MELLON
摘要:The present invention is directed to a process of atom (or group) transfer radical polymerization for the synthesis of novel homopolymer or a block or graft copolymer, optionally containing at least one polar group, with well defined molecular architecture and narrow polydipersity index, in the presence of an initiating system comprising (i) an initiator having a radically transferrable atom or group, (ii) a transition metal compound, and (iii) a ligand, the present invention is also directed to the synthesis of a macromolecule having at least two halogen groups which can be used as a macroinitiator component (i) to subsequently form a block or graft copolymer by an atom or group transfer radical polymerization process; the present invention is also directed to a process of atom or group transfer radical polymerization for the synthesis of a branched or hyperbranched polymer; in addition, the present invention is directed to a process of atom or group transfer radical polymerization for the synthesis of a macroinitiator which can subsequently be used to produce a block or graft copolymer.

标题 :Synthesis of vinyl polymers by controlled radical polymerization
发明人：WHITE DANIELA; O'DWYER JAMES B
权利人:PPG IND OHIO INC
摘要:A controlled free radical polymerization process, which includes the steps of: adding a monofunctional iniferter compound to an oxygen-free solvent; heating the solution to a temperature sufficient to allow the iniferter compound to form two carbon centered radical residues; adding a first monomer composition comprising one or more monomers to the solution containing the radical containing residues; polymerizing the first monomer composition to form a quasi-living polymer; and optionally polymerizing a second monomer composition comprising one or more monomers, which are different than the first monomer composition. The resulting non-random copolymer having the general formula:n nφ-[-A p -B s -] t -φn nwhere A and B are different compositions of ethylenically unsaturated monomers; p is an integer from 1 to 1,000; s is an integer from 0 to 1,000; t is an integer from 1 to 100; and φ is a residue from the iniferter.

标题 :Amine additive assisted enzymatic esterification of 1,2-diol monosulfonates
发明人：BOAZ NEIL W
权利人:EASTMAN KODAK CO
摘要:A process has been developed for the enzymatic esterification of 1,2-diol monosulfonates comprising contacting an ester; a 1,2-diol monosulfonate; an enzyme derived from a microorganism or animal organ which has stereoselective activity to asymmetrically esterify said 1,2-diol monosulfonate; in the presence of a nonhydroxylic organic solvent and an amine additive of the general formula R32R4N, wherein R3 may be the same or different and is selected from hydrogen or a straight or branched C1-C20 alkyl; and R4 is a straight or branched C1-C20 alkyl; or an unsubstituted or substituted C3-C20 aryl or heteroaryl group (with saisd substituent selected from C1-C4 alkyl, halogen, or C1-C4 alkoxy, and said hetero atom selected from nitrogen, sulfur, or oxygen); to produce a mixture of enantiomerically enriched unreacted 1,2-diol monosulfonate and the corresponding antipodal enantiomerically enriched ester. The resulting enantiomerically enriched products are useful chemical intermediates that may be employed in the synthesis of pharmaceutical and agricultural chemicals.
