标题:Process for the synthesis of exochelins
发明人：GAUDIOSO LARRY A; WEGLARZ MICHAEL A
权利人:KEYSTONE BIOMEDICAL INC
摘要:A process for the synthesis of an Exochelin comprising the steps of generating L-N-[(2-benzyloxy-(benzoyl)] serine or L-N-[2-benzyloxy (benzoyl)] threonine, creating L-N-t-Boc- epsilon -hydroxynorleucine and reacting same to produce L-N-Boc- epsilon -bromonorleucine trimethylsilylethyl ester, providing a dicarboxylic acid and forming an O-benzyl methyl hydroxamate from the dicarboxylic acid, coupling the O-benzyl methyl hydroxamate with the L-N-Boc- epsilon -bromonorleucine trimethylsilylethyl ester to give an L-N2-Boc-N6-methyl,N6-(benzyloxy) lysine 2-trimethylsilylethyl ester which incorporates the dicarboxylic acid as modified above, removing the N-tert-butoxycarbonyl protecting group from the L-N2-Boc-N6-methyl, N6-(benzyloxy) lysine 2-trimethylsilylethyl ester to yield a substituted lysine, and coupling the same with the L-N-[2-benzyloxy (benzoyl) serine or -threonine to yield a 2-trimethyl silylethyl ester of dibenzyl Exochelic acid, transforming the 2-trimethyl silylethyl ester of dibenzyl Exochelic acid to dibenzyl Exochelic acid, preparing benzyl epi-cobactin, forming an ester bond between the dibenzyl Exochelic acid and benzyl epi-cobactin to form an intermediate, and, hydrogenolytically removing three benzyl groups from said intermediate, resulting in the synthesized Exochelin. More particularly, a synthesis for Exochelin 786SM (R) is disclosed wherein the dicarboxylic acid is suberic acid and the serine form is utilized.

发明人：JASRA RAKSH VIR; TYAGI BEENA; MISHRA MANISH KUMAR
权利人:COUNCIL SCIENT IND RES
摘要:The present invention provides a green catalytic process for the synthesis of acetyl salicylic acid using solid acid catalysts at atmospheric pressure. The invention involve the solid acid catalyst such as sulfated transition metal oxides namely nano-crystalline sulfated zirconia, sulfated titania; modified zeolites namely zeolite H-beta, H-Y, H-ZSM-5 and K-10 montmorillonite clay in a solvent free environment using salicylic acid and acetic anhydride with yield about 95% and high selectivity (100%). The solid acid catalysts can be recovered, regenerated and reused.

发明人：UNGARELLI FABRIZIO; PIANI SILVANO
权利人:ALFA WASSERMANN SPA
摘要:A process for the synthesis of glycosaminoglycans in which one of the α-L-iduronic-2-O-sulfate acid saccharide units, which is characteristic of glycosaminoglycans with heparin or heparan structure, has undergone a structural modification, entirely or in part, with transformation into α-L-galacturonic acid substituted in position 3 with nucleophilic groups, is described. The process is carried out by treating glycosaminoglycans having heparin or heparan structure with a nucleophilic reagent in alkaline solution.
