摘要:
L-Thienylalanines are prepared via the hydantoin or the azlactone route. The starting substances used for the biotransformation are 2-hydroxy-3-thienylacrylic acids. The innovative step consists in the transamination of the enol form of the 2-hydroxy-3-thienylacrylic acids to give L-thienylalanines with the aid of biotransformation. The transaminiation is carried out in the presence of L-aspartic acid or L-glutamic acid as amino donor.

摘要:
A process for the production of 2-alkyl-3-aroyl-5-nitrobenzofurans by acylation of 2-(2-hydroxy-5-nitrophenyl)-1-aryl-ethanones and subsequent treatment of the esters with combinations of bases and proton acids or Lewis acids. This process can be used for the production of Dronedarone. Furthermore, novel intermediates for the manufacture of Dronedarone are provided.
摘要:
A process for the production of Dronedarone intermediates of the formula (I), by acylation of 2-(2-hydroxy-5-nitrophenyl)-1-(4-methoxyphenyl)-ethanone, subsequent treatment of the ester with bases and a zeolite (alumosilicate) catalyst and optional subsequent demethylation. This process can be used for the production of Dronedarone.
摘要:
Methods for the enzyme catalyzed acylation of primary and secondary alcohols using an enol ester as the acyl donor are described. The acylation occurs in organic media, and is enantioselective for racemic or prochiral alcohols. The reaction is irreversible, and produces unreactive by-products.
摘要:
The invention relates to conjugates which consist of mono- or polycarboxylated piperidine or pyrrolidine derivatives and pyranoses, furanoses or polyalcohols linked via a chain or a cyclic system. The carboxyl groups of the piperidine derivatives can either be located directly on the ring or linked to the ring via a short chain. The invention additionally relates to the preparation of these compounds and to their use for the production of pharmaceuticals and diagnostics.
摘要:
Process for the biotechnological preparation of L-thienylalanines in enantiomerically pure form from 2-hydroxy-3-thienylacrylic acids L-Thienylalanines are prepared via the hydantoin or the azlactone route. The starting substances used for the biotransformation are 2-hydroxy-3-thienylacrylic acids. The innovative step consists in the transamination of the enol form of the 2-hydroxy-3-thienylacrylic acids to give L-thienylalanines with the aid of biotransformation. The transaminiation is carried out in the presence of L-aspartic acid or L-glutamic acid as amino donor.
摘要:
The O-acylation of alcohols is carried out by reacting a vinyl ester or a carboxylic ester with Pseudomonas lipase immobilized on a hydrophobic carrier such as a polystyrene-based carrier. The polystyrene carrier preferably has a surface area of 100-1000 m.sup.2 /g, a pore volume of 25 to 75% and a pore diameter of 25-1200 .ANG.. Crosslinking may be carried out after the lipase is immobilized on the carrier.
