    • The invention relates to new 8.beta.-hydrazinomethyl-ergoline derivatives of the general formula (I), ##STR1## wherein x y stands for a ##STR2## or ##STR3## group, R stands for hydrogen or methyl group, andR.sub.1 stands for hydrogen, a lower acyl group, a di-(lower-alkylaminocarbonyl group, a group of the general formula (VI), ##STR4## wherein Z.sub.1, Z.sub.2 and Z.sub.3 each represent hydrogen, halogen or a trifluoromethyl group, or a group of the general formula (VII), ##STR5## wherein Y represents a lower alkyl group, allyl group or phenyl group, and acid addition salts thereof. These compounds possess valuable antiserotonine, antidepressant and hypotensive effects, furthermore they can be applied as starting substances in the preparation of other biologically active ergoline derivatives.The new compounds of the general formula (I) are prepared according to the invention by reacting the respective 6-methyl-8.beta.-mesyloxymethyl or -tosyloxymethyl-ergoline derivatives with dry hydrazine. In order to obtain the N-substituted hydrazinomethyl compounds, the N-unsubstituted derivatives are reacted with an acylating agent or with an isothiocyanate.
    • 本发明涉及通式(I)的新的8β-肼基甲基 - 麦角灵衍生物,其中xy代表基团,R代表氢或甲基,R1表示 代表氢,低级酰基,二 - (低级烷基氨基羰基,通式(VI)的基团,其中Z 1,Z 2和Z 3各自表示氢,卤素或三氟甲基, 或者通式(VII)的基团,其中Y代表低级烷基,烯丙基或苯基,及其酸加成盐,这些化合物具有有价值的抗塞冬糖,抗抑郁药和降压作用,而且它们 可以将其用作制备其它生物活性麦角灵衍生物的起始物质,通式(I)的新化合物根据本发明通过使各自的6-甲基-8β-甲氧基甲基或 - 苯甲氧基甲基 - 麦角灵衍生物 用干肼。 为了得到N-取代的肼基甲基化合物,N-未取代的衍生物与酰化剂或异硫氰酸酯反应。
