    摘要： The invention relates to new optically active or racemic 13-thia-prostacycline derivatives of the Formula I ##STR1## wherein R.sup.1 is hydrogen, a pharmaceutically acceptable cation or a straight or branched chain alkyl group having 1-5 carbon atoms;R.sup.2 is straight or branched chain alkyl having 4-9 carbon atoms or monosubstituted phenoxymethyl;--A--B-- is --CH.sub.2 --CH.sub.2 --, --CH.dbd.CH-- of Z-- or E-- configuration or --C.tbd.C--;one of the symbols X and Y is hydrogen, methyl or ethyl and the other is hydroxy, tetrahydropyranyoxy, 1-ethoxy-ethoxy or trialkylsilyloxy; orX and Y together form a --O--CH.sub.2 --CH.sub.2 --O-- group;Z is a sulfur atom or a --SO-- group.The compounds of the Formula I can be prepared by reacting a 13-thia-prostaglandine of the Formula III ##STR2## if desired after oxidation into the corresponding 13-oxide derivative--with a halogenating agent; and treating the 5-halogeno-13-thia-prostacycline of the Formula II ##STR3## thus obtained wherein E is halogen with an organic or inorganic base; and thereafter if desired removing the protecting groups X and/or Y and if desired converting a compound of the Formula I obtained into a salt or setting free the same from a salt. The new compounds of the Formula I possess anti-coagulant and hypotensive properties and can be used in therapy.

    摘要： A process for the preparation of optically active or racemic lactone diol derivatives of the formula ##STR1## (for use as intermediates in the Corey prostaglandin synthesis). Optically active or racemic lactone diol derivatives are inclosed, in whichR.sup.3 and R.sup.4 are the same or different and stand for a hydrogen, or a lower alkanoyl optionally substituted with one, two or three halogen atoms, or form together a ##STR2## group, in which R.sup.5 and R.sup.6 are the same or different and stand for a hydrogen, alkyl or aryl, with a process for preparing them.According to the invention the above compound are prepared by reacting optically active or racemic lactone of the formula II with formaldehyde or with a formaldehyde polymerisate, in the presence of the mixture of a strong acid and water or of a lower alkane carboxylic acid optionally substituted with one, two or three halogen atoms, and then optionally subjecting the obtained compound of the general formula I, in which R.sup.3 and/or R.sup.4 stand for an alkanoyl optionally substituted with one, two or three halogen atoms to partial or total hydrolysis or alcoholysis in an acid or alkaline medium and/or reacting it with the oxo-compounds of the formula R.sup.5 --CHO or R.sup.6 --CO--R.sup.5 or with the acetals of the above compounds.The compounds according to the invention are useful intermediates in the Corey prostaglandine synthesis.
