标 题 :Compositions for chemical synthesis of peptides
发明人：SEIFERT COLE
权利人:SEDERMA SA
摘要:The disclosure relates to compositions that can serve as anchors for the chemical synthesis of peptides. Anchor molecules can include GAP constituents, linker constituents, amino acid constituents, and/or stopper constituents. Anchor molecules can also include anchor peptides, wherein an anchor peptide can be removably coupled with an amino acid of a given sequence and act as a GAP anchor by achieving solubility control over the target peptide as it is synthesized via the addition of one or more other amino acids: the anchor peptide can then be removed from the target peptide. A novel method of peptide synthesis that utilizes novel anchor molecules and/or anchor peptides is also presented.

标题:Process for the recovery of the solvent and of the by-produced methylacetate in the synthesis of terephthalic acid
发明人：COSTANTINI GIUSEPPE; PAOLI PIETRO; SERAFINI MAURO
权利人:MONTEDISON SPA
摘要:The invention refers to an improved process for the recovery of the solvent and of the by-produced methylacetate in the synthesis of terephthalic acid, said synthesis being usually consisting of an oxidation of paraxylene with air, in the presence of a catalyst system composed by cobalt, manganese and bromine, in a solvent consisting of acetic acid, according to the equation (1): n n C.sub.6 H.sub.4 (CH.sub.3).sub.2 +3 O.sub.2 →C.sub.6 H.sub.4 n n (COOH) 2 =2 H 2 O (1) n More particularly, the improved process of this invention comprises the oxidation of para-xylene in acetic acid solution and in the presence of a catalytic system based on manganese, bromine and cobalt, whereby water is formed and methylacetate is by-produced during the oxidation, whereby solid terephthalic acid is separated from the mother liquor and whereby one withdraws from the oxidation zone a liquid which is obtained by condensing the vapors released during the oxidation and which are mainly consisting of acetic acid and water, the improvement consisting of the fact that: n (a) the liquid obtained by condensing the released vapors and said mother liquor are fed both to an azeotropic distillation system in which the azeotropic agent is isobutyl-acetate; n (b) the light ends of the azeotropic distillation, richer in water, are condensed and demixed into two phases, wherein the aqueous phase, which is lower and contains isobutyl-acetate and methyl-acetate, is conveyed to a stripping, whereby isobutyl-acetate and methyl-acetate are recovered, and wherein the organic phase is recycled to the azeotropic distillation.

摘要:The present invention relates to the synthesis of dimer alkaloid compounds, particularly those of the Catharantus (Vinca) family, from an indole unit, such as cantharanthine, and a dihydroindole unit, such as vindoline. A multi-step process is disclosed including the steps of (1) of 1,4-reduction of a first dimeric iminium intermediate to an enamine compound by reaction with a 1,4-dihydropyridine compound; (2) oxidative transformation of the resulting enamine to a second iminium intermediate under controlled aeration; (3) reduction of the second iminium intermediate to form the target dimer alkaloid compounds. The entire process can be conducted in a one-pot operation to obtain the target compounds without isolation of the intermediates.
