标题 :Tin Mediated Regioselective Synthesis of Sucrose-6-Esters
发明人：RATNAM RAKESH; MOFIZUDDIN MOHAMMED; AURORA SUNDEEP
权利人:PHARMED MEDICARE PRIVATE LTD A
摘要:A method is disclosed for regioselective synthesis of sucrose-6-acetate via formation of a novel sucrose-tin adduct using sucrose and DBTO. The novel tin adduct can be represented by a formula (6-O-sucrose)-O—Snbutyl.sub.2-O-(6-O-sucrose) or as 1,3.(di O-sucrose) dibutyl stannylene. The adduct is acylated to yield sucrose-6-acetate or sucrose-6-benzoate as major product.

摘要:The invention relates to the fields of fatty substance chemistry, specifically of the ceramide-type compound synthesis. The invention resides substantially in the synthesis of ceramide-type compounds. Specifically, the aim of the invention is a new enzymatic synthesis method, comprising at least one amidification step and one esterification step, achieved through lipases, among fatty acids and/or esters thereof and amino alcohols. The resulting ceramide-type compounds can be used as cosmetic and/or pharmaceutical compositions, in particular as dermatological compositions in conjunction or in admixture with one or more suitable cosmetic and/or pharmaceutical excipients or carriers. The method has an interest particularly in the synthesis of active compounds useful in the fields of cosmetology and/or pharmacology and specifically of dermatology.

摘要:A process for preparing unique peptide mixtures with a broad range of uses using combinations of natural and non-natural amino acid alkyl ester monomers and specific combinations of these monomers as dimers, trimers and higher oligomers selected from the large group of structural motifs that lead to useful physical and/or biological properties and that have been or may be identified from solid state peptide synthesis, isolation of peptides from natural sources, and production of peptides by recombinant DNA methods, or identification of peptides by recombinant methods such as phage display, the method of peptide synthesis comprising a) admixing one or more natural and non-natural amino acid alkyl ester monomer, dimer, trimer and higher oligomers with one or more proteases in a reaction medium; b) heating the mixture to between about 5° C. to about 90° C. for between 5 minutes and 24 hours; and c) recovering the formed oligopeptide.

摘要:A new method for preparing salts of metal cations and organic acids, especially divalent salts of alkaline earth metal ions from group II of the periodic system and carboxylic acids. The method comprising the use of a high temperature (about 90° or more) and, optionally. high pressure, in order to obtain a higher yield, purity and faster reaction speed than obtained with known synthesis methods. In particular, the present invention relates to the production of strontium salts of carboxylic acids. Novel strontium salts are also provided by the present method.
