摘要:
The present invention relates to a first biocatalytic process for preparing olodanrigan ((S)-5-(benzyloxy)-2-(2,2-diphenylacetyl)-6- methoxy-l,2,3,4-tetrahydroisoquinoline-3-carboxylic acid; compound of formula (I); EMA401, PD 126055 ) by reacting 3-(2-(benzyloxy) -3-methoxyphenyl)propenoic acid (compound of formula (C3)) with an engineered phenylalanine ammonia lyase (PAL) and an amino donor to (S)-2-amino-3-(2-(benzyloxy)-3-methoxyphenyl)propanoic acid (compound of formula (C4)), and then reacting the compound of formula (C4) to olodanrigan, or a salt, or a solvate thereof. The present invention also relates to a second biocatalytic p rocess for preparing olodanrigan by reacting the compound of formula (C3) with an engineered phenylalanine ammonia lyase (PAL) and an amino donor, and then adding an aldehyde derivative to form (S)-5- (benzyloxy)-6-methoxy-l,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (compound of formula (C5)), and then reacting the compound of formula (C5) to olodanrigan, or a salt, or a solvate thereof. The present invention further relates to a process for preparing pharmaceuticals and pharmaceutical compositions from the compound of formula (I), or a salt, or a solvate thereof. Olodanrigan is used in the treatment of neuropathic and inflammatory pain.La présente invention concerne un premier procédé biocatalytique de préparation d'olodanrigan d'acide ((S)-5-(benzyloxy)-2-(2,2-diphénylacétyl)-6-méthoxy-l,2,3,4-tétrahydroisoquinoléine-3-carboxylique ; composé de formule (I) ; EMA401, PD 126055) par réaction de l'acide 3-(2-(benzyloxy)-3-méthoxyphényl)propénoïque (composé de formule (C3)) avec une phénylalanine ammoniac lyase (PAL) génétiquement modifiée et un donneur d'amine à l'acide (S)-2-amino-3-(2-(benzyloxy)-3-méthoxyphényl)propanoïque (composé de formule (C4)), puis la réaction du composé de formule (C4) avec l'olodanrigan, ou un sel, ou un solvate de celui-ci.
