  • Patent number: 4299836
    Abstract: The invention relates to new ergol-8-ene and ergoline derivatives of the general formula /I/ ##STR1## wherein x y stands for --CH.dbd.C.dbd. or --CH.sub.2 --CH.dbd. group,R stands for hydrogen atom or methyl group,R.sub.1 stands for hydrogen or halogen atom,R.sub.2 stands for lower alkylsulfonyloxy group, phenylsulfonyloxy group optionally substituted with a lower alkyl group, or azido group,R.sub.3 stands for lower alkylsulfonyloxy group or phenylsulfonyloxy group optionally substituted with a lower alkyl group, and acid addition salts thereof. These compounds can be prepared from compounds of the general formula II ##STR2## wherein x y and R are as defined above, by reacting at least two equivalents of a lower alkylsulfonic acid chloride or phenylsulfonic acid chloride substituted with lower alkyl group.

  • Patent number: 3979405
    Abstract: This invention relates to compounds of the formula ##SPC1##WhereinR.sup.1 is hydrogen or an alkyl group having 1-4 carbon atoms;R.sup.2 but R.sup.3 are hydrogen and if both R.sup.4 and R.sup.5 are hydrogen, R.sup.2 and R.sup.3 are alkyl groups having 1-4 carbon atoms or hydroxymethyl groups;R.sup.4 and R.sup.5 are hydrogen but where both R.sup.2 and R.sup.3 are hydrogen, R.sup.4 but R.sup.5 stand for alkyl groups having 1-4 carbon atoms, are amino groups, which may be mono or di-substituted by alkyl groups having 1-4 carbon atoms, or are allyloxymethyl groups;X is an oxygen or sulphur atom or an NH group;Y stands for a halogen atom or a halogeno-substituted phenyl group. The disclosure also concerns a process for the preparation of such compounds.
