Abstract:
The resolution of racemic 1-(4-methoxybenzyl)-octahydro-isoquinoline, a key intermediate in the synthesis of the antitussive agent dextromethorphan, is reported using (R)-2-(6-methoxy-2-naphthyl) propionic acid in good yields. The resolving agent and the undesired isomer of the octahydro-isoquinoline have been recovered in good yield.
Abstract:
A compound represented by formula (I) or a pharmaceutically acceptable salt thereof has an effect of inhibiting CRTH2 and, therefore, is useful as a pharmaceutical.
Abstract:
The present invention is directed to processes for the synthesis of morphinans. In particular, a process for cyclizing a ß,Ϝ-bicyclic ketone compound to form a nordihydrothebainone product using the Grewe cyclization reaction is improved by forming a reaction mixture comprising a ß,Ϝ-bicyclic ketone compound, a cyclizing acid and a water scavenging cyclization additive. In one embodiment, the Grewe transformation occurs in the presence of an acid anhydride as the cyclization additive. Further, the present invention is directed to processes for converting a,ß-bicyclic ketone compounds (e.g., by-products of the Grewe cyclization reaction) to ß,Ϝ-bicyclic ketone compounds, wherein the ß,Ϝ-bicyclic ketone compounds may be recovered to further undergo Grewe cyclization and form the nordihydrothebainone product.
Abstract:
This invention provides a psychotropic agent, an analgesic, and/or an antiphlogistic, and a heath food that can safely take over a long period of time and is characterized by comprising, as an effective ingredient, a benzylisoquinoline derivative represented by general formula (I) or a bisbenzylisoquinoline derivative represented by general formula (II) or a pharmaceutically acceptable salt thereof.
Abstract:
The asymmetrical hydrogenation of 1-(4-methoxybenzyl)-3,4,5,6,7,8-hexahydroisoquinolinium salts to yield (S) or (R)-1-(4-methoxybenzyl)-1,2,3,4,5,6,7,8-hexahydroisoquinolinium salts can be effected with superior optical yield by the use of an iridium or rhodium complex catalyst comprising a chiral dipohsphine ligand of the general formula (I) or (II), (S)-1-(4-methoxybenzyl)-1,2,3,4,5,6,7,8-hexahydroisoquinoline and salts thereof are intermediate products in the manufacture of dextromethorphan, a known antitussive agent.
Abstract:
A commercial scale process for the production of tetrahydroisoquinolines and related heterocyclics by reaction, in mildly acidic conditions, of aryl N-sulfonylethylamines in the presence of suitable Lewis acid, and a compound capable of in situ generation of formaldehyde. The process is further characterized by formaldehyde being generated by the reaction of the Lewis acid upon the formaldehyde generating agent, instead of being present as an initial reactant. The process further avoids the presence of initial water which destroys the Lewis acid before it can act upon the formaldehyde generating agent.
Abstract:
The present invention relates to compounds of the formula (I) wherein X1 is wherein R?1, R2 and R10¿ are independently hydrogen or a suitable substituent; R?11 and R12¿ are independently hydrogen or a suitable substituent; R is unsaturated 5 to 6-membered heteromonocyclic group; A is direct bond or -NH-; X2 is monocyclic arylene, unsaturated 5 to 6-membered heteromonocyclic group or cycloalkenylene; Y is bivalent group selected from ethylene, trimethylene and vinylene, wherein CH2 is optionally replaced by NH or O, and CH is optionally replaced by N; and Z is -(CH¿2?)n-, -CO-(CH2)m-, -CH=CH- or -CO-NH-, wherein n is 1, 2 or 3 and m is 1 or 2, or a salt thereof. The compounds of the present invention inhibit apolipoprotein B (Apo B) secretion and are useful as a medicament for prophylactic and treatment of diseases or conditions resulting from elevated circulating levels of Apo B.
