hvor symbolene Z, G, m, n og q har de ovenfor angitte betydninger, og farmasøytisk akseptable salter derav. Disse forbindelsene med formel (I) er beskrevet i NO patent 158.577. Som nevnt ovenfor kan foreliggende mellomprodukter anvndes for fremstilling av slike terapeutisk aktive forbindelser (I), nærmere bestemt ved selektiv reduksjon av mellomproduktet (II) hvoretter beskyttelsesgruppene R3 og R4 fjernes for oppnåelse av tilsvarende forbindelse med formel (I). Forøvrig vises det til nevnte NO patent 158.577, også where the symbols Z, G, m, n and q have the meanings given above, and pharmaceutically acceptable salts thereof. These compounds of formula (I) are described in NO patent 158,577. As mentioned above, the present intermediates can be used for the production of such therapeutically active compounds (I), more specifically by selective reduction of the intermediate (II) after which the protective groups R3 and R4 are removed to obtain the corresponding compound of formula (I). Incidentally, reference is also made to the aforementioned NO patent 158,577

De beskyttende alkylgruppene R3 og R4 kan f.eks. fjernes ved spalting under anvendelse av en protlsk syre, f.eks. saltsyre eller hydrobromsyre ved en temperatur på 0-150°C, eller en Lewls-syre, f.eks. ved omsetning med et bortrlhalogenld i et hydrokarbonoppløsnlngsmlddel. The protective alkyl groups R3 and R4 can e.g. removed by cleavage using a protic acid, e.g. hydrochloric acid or hydrobromic acid at a temperature of 0-150°C, or a Lewls acid, e.g. by reaction with a boron halide in a hydrocarbon solvent.

Fremstillingen av foreliggende mellomprodukter (II) avhenger av typen av X]_, X2, X3 og X4. The production of the present intermediates (II) depends on the type of X]_, X2, X3 and X4.

Når Xi og Xg begge representerer CO, og X2 og X3 begge representerer CH2, kan forbindelsene med formel (II) fremstilles ved i rekkefølge å omsette en forbindelse med formel (III): When Xi and Xg both represent CO, and X2 and X3 both represent CH2, the compounds of formula (II) can be prepared by successively reacting a compound of formula (III):

hvor R5 representerer hydrogen eller en nitrogenbeskyttende gruppe som kan fjernes i nærvær av en amidbinding, alkylen CONH alkylen, og m, n og Z har den ovenfor angitte betydning, where R5 represents hydrogen or a nitrogen protecting group which can be removed in the presence of an amide bond, the alkylene CONH alkylene, and m, n and Z have the above meaning,

med forbindelsene med formlene (IV) og (V): with the compounds of formulas (IV) and (V):

i en hvilken som helst rekkefølge, in any order,

hvor I4 og L2 representerer lett avspaltbare grupper, og Q, G, R3 og R4 har den ovenfor angitte betydning. where I4 and L2 represent easily cleavable groups, and Q, G, R3 and R4 have the meaning indicated above.

Egnede nitrogenbeskyttende grupper R5 er velkjente Innen teknikken angående peptidsyntese og innbefatter f.eks. alkoksykarbonylgrupper, f.eks. etoksykarbonyl. Suitable nitrogen protecting groups R5 are well known in the art regarding peptide synthesis and include e.g. alkoxycarbonyl groups, e.g. ethoxycarbonyl.

Lett avspaltbare grupper L^ og L2 innbefatter f.eks. halogen, f.eks. klor eller brom; 1-imidazolyl, trifluormetansulfonat, alkylkarbonat, f.eks. etylkarbonat: benzylkarbonat, alkanoyl-oksy, f.eks. acetyl; eller trifluoracetoksy. Easily cleavable groups L^ and L2 include e.g. halogen, e.g. chlorine or bromine; 1-imidazolyl, trifluoromethanesulfonate, alkyl carbonate, e.g. ethyl carbonate: benzyl carbonate, alkanoyloxy, e.g. acetyl; or trifluoroacetoxy.

Reaksjonen kan utføres i et oppløsningsmiddel som er inert ved reaksjonsbetingelsene, f.eks. et klorert hydrokarbon, f.eks. kloroform, i nærvær av en ikke-nukleofil base, f.eks. trietylamin. Reaksjonen kan utføres ved en temperatur fra ca. 0 til 100°C. The reaction can be carried out in a solvent which is inert under the reaction conditions, e.g. a chlorinated hydrocarbon, e.g. chloroform, in the presence of a non-nucleophilic base, e.g. triethylamine. The reaction can be carried out at a temperature from approx. 0 to 100°C.

De frie syrene tilsvarende forbindelsene med formel (IV) og (V), dvs. når og L2 begge er lik hydroksy, kan omsettes, f.eks. med tionylklorid, etylklorformiat eller N,N'-karbonyl-diimidazol for omdannelse av kaboksylgrupper til en gruppe The free acids corresponding to the compounds of formula (IV) and (V), i.e. when and L2 are both equal to hydroxy, can be reacted, e.g. with thionyl chloride, ethyl chloroformate or N,N'-carbonyldiimidazole to convert carboxyl groups into a

—COLi eller —COL2. respektivt. —COLi or —COL2. respectively.

Når X2 og X3 begge representerer CO, og X^ og X4 begge representerer CH2, kan for.bindelsene med formel (II) fremstilles ved i rekkefølge å omsette gruppene L3 og L4, i hvilken som helst rekkefølge, i forbindelsen med formel (VI): When X 2 and X 3 both represent CO, and X 2 and X 4 both represent CH 2 , the compounds of formula (II) can be prepared by sequentially reacting the groups L 3 and L 4 , in any order, in the compound of formula (VI) :

hvor L3 representrerer en lett avspaltbar gruppe, og L4 representerer enten en lett avspaltbar gruppe eller en gruppe som lett kan omdannes til en lett avspaltbar gruppe, og m, n og z har den ovenfor angitte betydning, med forbindelsene med formlene (VII) og (VIII): where L3 represents an easily cleavable group, and L4 represents either an easily cleavable group or a group that can be easily converted into an easily cleavable group, and m, n and z have the meaning given above, with the compounds of the formulas (VII) and ( VIII):

hvor q, G, R3 og R4 har den ovenfor angi;tte betydning. where q, G, R3 and R4 have the meaning indicated above.

Lett avspaltbare grupper som L3 og L4 innbefatter dem som er beskrevet ovenfor for L^ og L2 • Når i L4 representerer en gruppe som kan omdannes til en lett avspaltbar gruppe, innbefatter slike omdannbare grupper alkoksy, f.eks. etoksy, metoksy; og hydroksy. Omdannelsen kan 1 foretas ved bruk av konvensjonelle teknikker. Readily leaving groups such as L3 and L4 include those described above for L^ and L2 • When in L4 represents a group which can be converted into a readily leaving group, such convertible groups include alkoxy, e.g. ethoxy, methoxy; and hydroxy. The conversion can be carried out using conventional techniques.

Det er foretrukket å utføre erstatningsrekkefølgen for L3 og L4 som følger: med L4 som en gruppe som kan omdannes til en avspaltbar gruppe, kan L3 omsettes med en forbindelse med formel (VII) eller formel (VIII). L4 omdannes da til'en lett avspaltbar gruppe og omsettes med den gjenværende forbindelse med formel (VII) eller formel (VIII). It is preferred to carry out the substitution order for L3 and L4 as follows: with L4 as a group which can be converted into a leaving group, L3 can be reacted with a compound of formula (VII) or formula (VIII). L4 is then converted into an easily cleavable group and reacted with the remaining compound of formula (VII) or formula (VIII).

Reaksjonene kan utføres under betingelser i likhet med dem som er beskrevet ovenfor når X^ og X2 begge representerer CO. The reactions can be carried out under conditions similar to those described above when X 1 and X 2 both represent CO.

Når både X^ og X3, eller både X2 og X4 .representerer CO, og de gjenværende av X^, X2t X3 og X4 representerer CH2, kan de tilsvarende forbindelser med formel (II) fremstilles ved sekvensmessig omsetning i hvilken som helst rekkefølge med nitrogenfunksjonen og karbonylfunksjonenntil forbindelsen med formel (IX): When both X^ and X3, or both X2 and X4, represent CO, and the remainder of X^, X2, X3, and X4 represent CH2, the corresponding compounds of formula (II) may be prepared by sequential reaction in any order with the nitrogen function and the carbonyl function of the compound of formula (IX):

hvor R5, L, m, n og Z har den ovenfor angitte betydning; med forbindelsene med enten formel (IV) eller formel (VIII), eller forbindelsene med formel (VII) oggformel V, som defi-nert ovenfor. where R5, L, m, n and Z have the above meaning; with the compounds of either formula (IV) or formula (VIII), or the compounds of formula (VII) and formula V, as defined above.

En typisk fremgangsmåte er som følger. A typical procedure is as follows.

med L4 som en avspaltbar gruppe og R5 som en beskyttende gruppe, kan en forbindelse med formel (IX) omsettes med en forbindelse med formel (VIII), fulgt av omdannelse av R5 fra en beskyttende gruppe til et hydrogen, og fremgangsmåten avsluttes ved omsetning av denne forbindelse med en forbindelse med formel (IV), for oppnåelse av en forbindelse med formel (II), hvori X^ og X3 hver representerer CO, og X2 og X4 representerer CH2 • with L4 as a leaving group and R5 as a protecting group, a compound of formula (IX) can be reacted with a compound of formula (VIII), followed by conversion of R5 from a protecting group to a hydrogen, and the process is terminated by reaction of this compound with a compound of formula (IV), to obtain a compound of formula (II), in which X^ and X3 each represent CO, and X2 and X4 represent CH2 •

Reaksjonene kan utføres under betingelser lik dem som er beskrevet ovenfor, for fremstillingen av forbindelser med formel (II) når X^ og X2 begge representerer CO. The reactions can be carried out under conditions similar to those described above for the preparation of compounds of formula (II) when X 1 and X 2 both represent CO.

Forbindelsene med formlene (III), (IV), (V), (VI), (VII), (VIII) og (IX) er enten kjente, eller kan fremstilles fra kjente forbindelser under anvendelse av i og for seg kjente teknikker. The compounds with the formulas (III), (IV), (V), (VI), (VII), (VIII) and (IX) are either known, or can be prepared from known compounds using techniques known per se.
