摘要:A method of solid-state synthesis of peptides that provides a polymeric solid-state synthesis support, attaches a first amino acid to said support to form the first amino acid molecule of the desired peptide chain, attaches additional amino acids to form the desired peptide chain, characterized in that the polymeric solid-state synthesis support is a styrenic polymer containing at least 50 mol % divinylbenzene monomer units, the styrenic polymer being functionalized with chloromethyl and/or benzyloxybenzyl alcohol and/or amino moieties, and having porosity 60-90% and medium pore diameter ranging from 10 to 80 nm. A functionalized styrenic polymer is claimed.

摘要:A method for the synthesis of cyclic acetals comprises reacting at least one carbonyl-function compound selected from aldehydes, ketones, and/or linear acetals, on a polyol in a concentrated aqueous solution exceeding 20 wt % in a reactor containing an acidic catalyst. The carbonyl-function compound is selected so that the cyclic acetal obtained has a water solubility lower than 20000 mg/kg. During the catalytic reaction for the cyclic acetal synthesis, at least one portion of the organic phase containing the cyclic acetal is separated. The acidic catalysis is either homogeneous when using a water-soluble strong acid, or heterogeneous when using a solid acid such as a resin, a zeolite, or any appropriately acidified solid. The extractive reaction method can be used for obtaining high conversions and selectivity.

摘要:The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.
