标题 :Process for the Synthesis of Fluorinated Conductive Salts for Lithium Ion Batteries
发明人：ZHOU CHANGYUE; DU HONGJUN; WU WENTING
权利人:FUJIAN YONGJING TECH CO LTD
摘要:The invention relates to a new process for the synthesis of fluorinated conductive salts for lithium ion batteries (Li-ion batteries). The said fluorinated conductive lithium ion (Li-ion) battery salts of interest in the framework of the present inventions synthesis process, for example, are Li-ion salts such as LiFSI (lithium bis-(fluoromethanesulfonlyl) imide), LiTFSI (lithium bis-(trifluormethanesulfonlyl) imide), and LiTFSFI (lithium trifluoromethanesulfonylfluorosulfonyl imide), with the formulas as displayed in the Table I herein below. LiFSI, LiTFSI and LiFSTFSI are the most promising conducting salts for Lithium ion batteries and essential for future electromobility.

摘要:The present invention relates to a method for the synthesis of 7-ethyl-10-[4-(1-piperidino)-1-piperidino]carbonyloxycamptothecin (i.e. iriniotecan), comprising: (a) preparing 10-[4-(1-piperidino)-1-piperidino]carbonyloxycamptotecin; and (b) selectively ethylating the compound of step (a) at the 7-position, thus resulting in the preparation of 7-ethyl-10-[4-(1-piperidino)-1-piperidino]carbonyloxycamptothecin. The present invention is further directed to the use of 10-[4-(1-piperidino)-1-piperidino]carbonyloxycamptothecin (i.e. 7-des-ethyl-irinotecan) as intermediate in a method for the synthesis of irinotecan as described.

标 题:Synthesis of pancratistatin prodrugs
发明人：PETTIT GEORGE R; ORR BRIAN; DUCKI SYLVIE
摘要:A new and efficient synthesis of the (+)-pancratistatin phosphate prodrug 2 a has been accomplished. Selective protection (tetraacetate 4 ) of (+)-pancratistatin ( 1 a ) was followed by phosphorylation (to 5 ) with dibenzyl chlorophosphite (prepared in situ from dibenzyl phosphite). Cleavage of the acetate (with sodium methoxide) and benzyl (by hydrogenolysis) protecting groups followed by concomitant reaction with two equivalents of sodium methoxide afforded good yield of disodium (+)-pancratistatin phosphate ( 2 a ). Further increases in yields of the prodrug ( 2 a ) were realized by avoiding heat in the final purification steps. Fourteen ( 2 b - o ) additional metal and ammonium derived phosphate prodrugs were also synthesized.

摘要:The present invention discloses a process for dimethylation of active methylene groups. Specifically, the invention discloses a process for preparing 3-amino-2,2-dimethylpropanamide. Compounds produced by the present dimethylation process such as 3-amino-2,2-dimethylpropanamide can be used as intermediates in the route of synthesis of therapeutic, prophylactic or diagnostic agent, for example aliskiren or cryptophycin. Particularly, the invention relates to embodiments further extending to processes for preparing pharmaceutical dosage form comprising said therapeutic, prophylactic or diagnostic agents. More specifically, the invention relates to the use of compounds produced by the present dimethylation process for the manufacture of therapeutic, prophylactic or diagnostic agents or for the manufacture of pharmaceutical dosage forms comprising said therapeutic, prophylactic or diagnostic agents. The processes according to the present invention can be beneficially applied for the synthesis of various active pharmaceutical ingredients, such as aliskiren or crypthophycin.
