标 题 :Synthesis of stable quinone and photoreactive ketone phosphoramidite reagents for solid phase synthesis of photoreactive-oligomer conjugates
发明人：FENSHOLDT JEF
权利人:EXIQON AS
摘要:Quinone phosphoramidite reagents as well as photoreactive ketone phosphoramidite reagents, such as anthraquinone phosphoramidite reagents and benzophenone phosphoramidite reagents were synthesized and used for the solid phase synthesis of photoreactive-oligonucleotide conjugates. These phosphoramidite reagents are stable, suitable for large-scale synthesis and designed for automated solid phase synthesis of oligomers terminating in a photoreactive moiety.

标题:Process for selective synthesis of enantiomers of substituted 1-(2-amino-1-phenyl-ethyl)-cyclohexanols

摘要:A process for the enantioselective synthesis of an (S)- or (R)-1-[2-dimethylamino)-1-(methoxyphenyl)ethyl]cyclohexanol and analogues or salt thereof are described. The method involves the steps of (a) reacting an (S) or (R) 4-benzyloxazolidinone with a mixed anhydride of a methyoxyphenylacetic acid under conditions which form a oxazolidinone, (4S)- or (4R)-4-benzyl-3-[methyoxyphenyl]acetyl]-oxazolidin-2-one, (b) treating the (4S)- or (4R)-4-benzyl-3-[(methoxyphenyl)acetyl]-1,3-oxazolidin-2-one with an aprotic amine base and titanium chloride in a chlorinated solvent under conditions which permit formation of the corresponding anion, (c) mixing the corresponding anion with titanium chloride and cylcohexanone under conditions which permit an aldol reaction to form the corresponding (4S)- or (4R)-4-benzyl-3-[(2R)-2-(1-hydroxycyclohexyl)-2-(methoxyphenyl)acetyl]-1,3-oxazolidin-2-one,(d) hydrolyzing the (4S)— or (4R)-4-benzyl-3-[(2R)-2-(1-hydroxycyclohexyl)-2-(methoxyphenyl)acetyl]-1,3-oxazolidin-2-one to form a chiral acid (2S or 2R)-(1-hydroxycyclohexyl)-methoxyphenyl)acetic acid, (e) coupling the chiral phenylacid to a secondary amine to form an amide, and (f) reducing the amide to form an (S) or (R) 1[2-dimethylamino)-1-(methoxyphenyl)ethyl]cyclohexanol or a salt thereof.

标 题 :Synthesis of hpGRF(Somatocrinin) in liquid phase and intermediate peptides
发明人：DIAZ JOSEPH; DEMARNE HENRI; RONCUCCI ROMEO; SCHMELCK PAUL-HENRY
权利人:SANOFI SA
摘要:The invention relates to synthesis of hpGRF (Somatocrinin) in liquid phase and to intermediate peptides, comprising: coupling, one after the other and in the order of the sequence of the GRF, the fragments in which: (a) the side acid functions of the aspartic and glutamic acids and the side amine function of the lysine are protected by protector groups stable in the conditions of deprotection of the group Boc, (b) the guanidine function of the arginine is protected by protonation, and (c) the N-terminal amino acid is protected on the amine by the Boc group; selectively eliminating the group Boc from the N-terminal amine of the peptide in phase of elongation by hydrolysis with trifluoroacetic acid, said coupling being effected in an aprotic polar solvent and eliminating, at the end of sequence, all the protector groups by hydrolysis with the aid of a 0.1 to 1M solution of methanesulfonic or trifluoromethanesulfonic acid in trifluoroacetic acid.
