标题 :Methods for the synthesis of α- hydroxy-β-amino acid and amide derivatives
发明人：SEMPLE JOSEPH E; LEVY ODILE E
权利人:CORVAS INT INC
摘要:Methods for the synthesis of alpha-hydroxy-beta-amino acid and amide derivatives and alpha-ketoamide derivatives and novel derivatives made by these methods are provided. These methods involve reacting a N-terminally blocked (protected) aminoaldehyde with an isonitrile and a carboxylic acid to give an amino-alpha-acyloxy carboxamide. The acyloxy group may be removed to give the derivative. Alternatively the protecting group is removed and acyl shift occurs to give the derivative. These derivatives are useful in the synthesis of compounds such as peptidyl alpha-ketoamides and alpha-hydroxy-beta-carboxylic acid and amide derivatives. Certain of these compounds have been reported to have activity as inhibitors of proteases, such as serine proteases and cysteine proteases.

标 题 :Synthesis of Tetracyclines and intermediates thereto

摘要:The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The recent development of a modular synthesis of tetracycline analogs through a chiral enone intermediate has allowed for the efficient synthesis of novel tetracycline analogs never prepared before. The present invention provides more efficient routes for preparing the enone intermediate and allows for substituents at positions 4a, 5, 5a, and 12a of the tetracycline ring system.

标题 :Synthesis of peptides and proteins
发明人：ERICKSON BRUCE W
权利人:UNIV ROCKEFELLER
摘要:Solid phase synthesis of peptides and proteins have been improved by the use of a trifunctional segment, one functional group of which is bound to a solid support, the other two functional groups being available as substrates upon which identical proteins are synthesized.

摘要:The present invention relates to a specific process for the diastereoselective synthesis of rac-diorganosilylbis(2-methylbenzo[e]indenyl)zirconium compounds of the formula I, n nby reacting the silyl-bridged bisindenyl ligand with a dihalozirconium bis(3,5-di-tert-butylphenoxide)-base adduct to form the diorganosilylbis(2-methylbenzo[e]indenyl)zirconium bis(3,5-di-tert-butylphenoxide) and subsequently replacing the phenoxide groups by X using suitable replacement reagents to give the compound of the formula I; where the substituents X can be identical or different and are each F, Cl, Br, I or linear, cyclic or branched C 1-10 -alkyl; and the substituents R can be identical or different and are each linear, cyclic or branched C 1-10 -alkyl or C 6-10 -aryl; and also to the use of these compounds as catalysts.

摘要:The invention concerns a temperature-stable labelling reagent of formula (I), wherein: R<1> represents H or an alkyl, aryl or substituted aryl group; R<2> represents a detectable marker or at least two detectable markers linked together by at least a multimeric structure; L is a linking arm comprising a linear catemer concatenation of at least two covalent bonds; and n is an integer equal to 0 or 1; R<3> and R<4> represent, independently of each other: H, NO2, Cl, Br, F, I, R<2>-(L)n-Y-X-, OR, SR, NR2, R, NHCOR, CONHR, COOR with R = alkyl or aryl, A is a linking arm comprising at least a double bond enabling the conjugation of the diazo function with the aromatic cycle; and u is a whole number between 0 and 2, preferably between 0 and 1; and -Y-X- represents -CONH-, -NHCO-, -CH2O-, -CH2S-. The invention also concerns a method for the synthesis of said markers and uses for labelling biological molecules, in particular nucleic acids, with a labelling reagent bearing the diazomethyl function. The invention is particularly applicable in the field of diagnosis.
