Denne forbindelsen kan brukes direkte for å oppnå forbindelsene med formel (A) hvori R^betegner en lavere alkylgruppe. Den vil bli debenzylert om det er ønsket for å oppnå intermediatet med formel I hvori X og R-^begge representerer hydrogen; This compound can be used directly to obtain the compounds of formula (A) in which R₁ denotes a lower alkyl group. It will be debenzylated if desired to obtain the intermediate of formula I wherein X and R-^ both represent hydrogen;
med hensikt å fremstille forbindelsene med formel (A) hvori R^betegner hydrogen. with the intention of preparing the compounds of formula (A) in which R^ denotes hydrogen.
Alkoholene med formel II, utgangspunktet i fremstillingen, fremstilles fra 4-klor-l-H-pyrrolo-(3,2-c)-pyridiner substituert i 1-posisjon ved fremgangsmåten som er beskrevet av E. Bisagni et Coll. (Tétrahedron, 39, 1777-1781, (1983)), imidlertid med bruk av dietyleter som oppløsningsmiddel i det tilfelle der substituenten er en benzylgruppe. The alcohols of formula II, the starting point in the preparation, are prepared from 4-chloro-1-H-pyrrolo-(3,2-c)-pyridines substituted in the 1-position by the method described by E. Bisagni et Coll. (Tétrahedron, 39, 1777-1781, (1983)), however with the use of diethyl ether as solvent in the case where the substituent is a benzyl group.
Oksyderingen av alkoholene til acetylerte derivater med formel (III) utføres med mangandioksyd i et klorert oppløsnings-middel, med tilbakeløp. The oxidation of the alcohols to acetylated derivatives of formula (III) is carried out with manganese dioxide in a chlorinated solvent, with reflux.
Overføringen til krotonesteren med formel (IV) skjer vedThe transfer to the croton ester of formula (IV) takes place by
å omsette derivatet med formel (III) i oppløsning i et inert oppløsningsmiddel såsom 1,2-dimetoksyetan, ved en temperatur mellom 0°C og 90°C, med etyldietylfosfonoacetat på forhånd gjort basisk med natriumhydrid. En cis-trans-blanding av etylesteren av krotonsyre med formel (IV) dannes. reacting the derivative of formula (III) in solution in an inert solvent such as 1,2-dimethoxyethane, at a temperature between 0°C and 90°C, with ethyldiethylphosphonoacetate previously made basic with sodium hydride. A cis-trans mixture of the ethyl ester of crotonic acid of formula (IV) is formed.
Denne esteren forsåpes direkte til 3-(4-klor-l-H-pyrrolo-(3, 2-c)-'2-pyrridyl) krotonsyre med formel (V). This ester is saponified directly to 3-(4-chloro-1-H-pyrrolo-(3,2-c)-'2-pyrridyl) crotonic acid of formula (V).
Denne syren overføres til et blandet anhydrid i acetonopp-løsning, ved innvirkning av etylklorkarbonat ved lav temperatur i nærvær av et tertiært alifatisk amin, deretter til et azid med formel (VI) ved innvirkning av natriumnitrid i vandig opp-løsning ved lav temperatur. This acid is transferred to a mixed anhydride in acetone solution, by the action of ethyl chlorocarbonate at low temperature in the presence of a tertiary aliphatic amine, then to an azide of formula (VI) by the action of sodium nitride in aqueous solution at low temperature.
Azidet i oppløsning i et inert oppløsningsmiddel såsom difenyleter gjøres ringformet ved oppvarming til høy temperatur i nærvær av et tertiært alifatisk amin med høyt kokepunkt, såsom tributylamin. Således fremkommer forbindelser med formel (I) hvori X betegner klor og R^ er en lavere alkyl- eller benzyl-gruppe. The azide in solution in an inert solvent such as diphenyl ether is cyclized by heating to a high temperature in the presence of a high boiling tertiary aliphatic amine such as tributylamine. Compounds of formula (I) are thus produced in which X denotes chlorine and R 1 is a lower alkyl or benzyl group.
Ved hydrogenering, ved omgivelsenes temperatur og trykk,During hydrogenation, at ambient temperature and pressure,
i nærvær av en katalysator såsom palladisert trekull, fremkommer forbindelser med formel (I) hvori X betegner hydrogen og R^fremdeles er en lavere alkyl- eller benzyl-gruppe. in the presence of a catalyst such as palladated charcoal, compounds of formula (I) are produced in which X denotes hydrogen and R is still a lower alkyl or benzyl group.
For å oppnå forbindelsene med formel (I) hvori R^betegner hydrogen, utsettes forbindelsene hvori R^betegner en benzyl-gruppe, for debenzylering: denne reaksjonen skjer ved innvirkning av natrium i flytende ammoniakk. To obtain the compounds of formula (I) in which R^ denotes hydrogen, the compounds in which R^ denotes a benzyl group are subjected to debenzylation: this reaction takes place by the action of sodium in liquid ammonia.
