A 9, .9 la Prostaglandin E 2 is a naturally occurring substance which has many physiological actions. For example, it inhibits gastric acid secretion and provides gastrointestinal cytoprotection, lowers blood pressure, stimulates and relaxes smooth muscle, inhibits platelet aggregation and inhibits lipolysis.
Synthetic PGE 2 analogues offer the possibility of different potency, longer duration of activity and increased selectivity of action and are therefore of considerable interest.
Many different PGE 2 analogues have been suggested in the past for use in medicine but in only one instance have 13-oxa compounds been proposed in this respect. Thus, British Patent Specification 2082176A describes a group of compounds which includes 2-(heptyloxy)-3-hydroxyacid and a 15-hydroxy derivative thereof.
These compounds are stated to inhibit blood platelet aqqreqation and have bronchodilatory activity, and are proposed for use as antithrombotic or antiasthmatic agents.
-11 We have now found e new group of cyclopentyl ethers that have
PGE
2 -type activity. Compounds in this class have a particularly useful profile of biological action. In particular they have shown high potency and extended duration of action as regards the inhibition of gastric acid secretion and gastrointestinal cytoprotection and are therefore of interest in the treatment of ulcers.

Compounds of formula inhibit gastric acid secretion, as determined for example by their ability to inhibit histamine-induced secretory responses in the rat perfused stomach, following the method of Ghosh M.N. and Schild in Br.J.Pharmacol., 1958, 13, 54 as modified -1 25 by Parsons Ph.D Thesis, University of London, 1969.
The compounds also provide gastrointestinal cytoprotection, as determined for example by their ability to inhibit ethanol-induced lesions in the conscious rat, following the method of Robert et al in Gastroenterology, 1979, 77, 433, modified by the use of let r: indomethacin prior to the administration of the test compound.
'he compounds are thus of interest in the prevention and/or treatment of ulcers. They may also be used in the treatment of other S cnditions which arise from the hypersecretion of gastric acid. They may be formulated in conventional manner with one or more pharmaceutical carriers, for example for oral, buccal, parenteral or rectal administration.
:i 8 The compounds may be formulated for oral administration as, for example, tablets, capsules, powders, solutions or syrups prepared by conventional means with acceptable excipents.
The compounds may be formulated for parenteral administration by bolus injections or continuous infusion. Formulations for injections may be presented in unit dosage form in ampoules, or in multi-dose containers, with an added preservative.
For buccal administration, the compounds may be formulated as tablets or lozenges in conventional manner; and for rectal administration compositions such as suppositories or retention enemas, for example containing conventional suppository bases such as cocoa butter or other glyceride, can be used.
The compounds are preferably administered orally, for example in amounts of 0.5 to 300 pg/kg body weight, 1 to times daily. For parenteral administration, the compounds may be administered in amounts of 0.01 to 10pg/kg body weight, 1 to 4 times daily. The precise dose will of course depend on the age and condition of the patient.
Suitable methods for preparing the compounds of the invention are described below, the various groups and symbols being as defined above except where otherwise indicated.
Compounds of formula may be prepared by deprotection of a corresponding compound in which the ring hydroxy group and the hydroxy (group in Y are protected.

8 The two R 8 groups in the compounds of formula are conveniently the same, but they may be different if desired.
Where R 8 is tri(hydrocarbyl)silyl the hydrocarbyl substituents may be the same or different e.g. C 1 -6 alkyl, C2-6 alkenyl, C3-7 cycloalkyl, C 7 20 aralkyl and C 6 20 aryl groups. Such groups include methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, t-butyl, allyl, phenyl and benzyl. Preferred hydrocarbyl groups are C 1 -4 alkyl, e.g.
methyl and t-butyl. Trimethylsilyl and t-butyldimethylsilyl groups are particularly preferred.
When R 8 is an arylmethyl group it may contain up to 20 carbon atoms, e.g. benzyl, diphenylmethyl or triphenylmethyl.
The method used to deprotect the protected hydroxyl group will 20 depend on the nature of R 8 but in general acid hydrolysis or reduction may be used.
Thus, for example when R 8 is a tetrahydropyran-2-yl, tetrahydrofuran-2-yl or ethoxyethyl group deprotection may be carried f« t out with an acid. Suitable acids include inorganic acids such as hydrochloric acid and organic acids such as acetic acid or trifluoroacetic acid. Suitable solvents include ethers diethyl ether, dioxan and tetrahydrofuran) halogenated hydrocarbons (e.g.
dichloromethane, hydrocarbons toluene), dipolar aprotic solvents acetone, acetonitrile, dimethylsulphoxide and 30 dimethylformamide) and alcohols methanol, ethanol and ethylene gylcol). Where desired the solvents may be used in combination with water. The reaction may be carried out at any suitable temperature, such as from 00 to 50 0 C, e.g. 400 to 50 0
C.
A tri(hydrocarbyl)silyl group may for example be removed by acid t 35 hydrolysis, e.g. with dilute mineral acid or trifluoroacetic acid or by treatment with fluoride ions from a quaternary ammonium 10 fluoride such as tetra-n-butyl ammonium fluoride), or by treatment with aqueous hydrogen fluoride. Arylmethyl grops may b( removed by reduction, e.g. by hydrogenolysis, e.g. with a nu)le metal catalyst such as platinum or palladium, or by treatment with a Lewis acid (e.g.
boron trifluoride-etherate) in the presence of a thiol (e.g.
ethanethiol) in a suitable solvent such as dichloromethane at e.g.
room temperature.

Alternatively, the oxidation may be carried out with dimethylsulphoxide, activated by N,N'-dicyclohexylcarbodiimide, in the presence of pyridinium trifluoroacetate in a solvent such as dichloromethane at e.g. -100C to room temperature. Other conventional oxidative methods can also be used, for example Jones reagent.
Intermediate compounds of formula may be prepared by the methods generally described in European Patent Specification 160495.
It will be appreciated that the deprotection method is usually applied in connection with the formation by oxidation of the q cyclopentyl ring oxo group. Thus, the compounds of formula may J generally be prepared by oxidising a corresponding compound of formula The formation of the ring oxo group may however be effected prior to the introduction of the desired R 1 group by esterification by Smethod below) and the protecting groups removed thereafter.
C r€ Ij 11 Compounds of formula may also be prepared by esterifyinq the corresponding carboxylic acids, i.e. the compounds in which R 1 is a hydrogen atom, by conventional methods.
Thus for example a compound of formula may be prepared by conversion of the corresponding carboxylic acid into an activated derivative a corresponding mixed anhydride) formed for example by reaction with an alkyl chloroformate isobutyl chloroformate) or an acid chloride pivaloyl chloride) in the presence of a suitable base triethylamine or pyridine). The activated derivative can then be reacted with an appropriate compound R 1

which are either known compounds or may be prepared by methods analogous to those used for the preparation of known compounds.
Suitable solvents include dipolar aprotic solvents acetone, acetonitrile and dimethylformamide) and halogenated hydrocarbons (e.g.
dicloromethane). The reaction may be carried out at any suitable temperature e.g. from OOC to room temperature.
The same group of compounds of formula may also be prepared by first reacting the corresponding carboxylic acid with dicyclohexylcarbodiimide in the presence of 4-dimethylaminopyridine and then treating the product with a phenol R 1 OH. This reaction is conveniently performed at an appropriate temperature 0 0 C to room temperature) in a solvent such as ether or dichloromethane.
The carboxylic acids required as starting materials for this reaction may be prepared by the methods generally described in European Patent Specification 160495.

Compounds of formula in which X is a -CH=CH- group may be prepared by selective reduction of a corresponding compound in which X is an acetylene group. Suitable methods of reduction include hydrogen 35 in the presence of a catalyst, e.g. palladium on a support CaC0 3 or BaSO 4 and poisoned for example by lead or quinoline.

The acetylenes required as starting materials may be prepared from the corresponding acetylenic acids by esterification using the methods described above. The acetylenic acid intermediates may be prepared by the methods generally described in European Patent Specification 160495.
Compounds of formula in which X is a trans -CH=CH- group may be prepared by isomerisation of a corresponding compound in which X is a cis -CH=CH- group.
The isomerisation may for example be effected by treating the corresponding cis compound with toluene-p-sulphinic acid in dioxan at reflux), or azobisisobutyronitrile and thiophenol, using for example a hydroarbon solvent benzene) at any suitable temperature up to reflux.
The processes in methods may also be applied to compounds of formula and and the products subsequently converted into compounds of formula by the methods described above.
When a specific enantiomer of formula is required, starting materials having the desired stereochemical configuration should be used in the above processes. Such starting materials may be prepared for example using the methods dscribed in European Patent Specification 160495 from an enantiomeric intermediate as described in European Patent Specification 74856.
