    • This invention relates to a process for preparing pergolide, which comprises the steps of reacting 9,10-dihydrolysergol with an acid anhydride at an elevated temperature in the presence of a catalyst to form a triacylated product intermediate; reducing the triacylated product intermediate with a reducing agent in a solvent to form a primary amino alcohol intermediate; and reacting the amino alcohol intermediate with dimethyl disulfide and trialkyl phosphine, aryl phosphine or the polymeric derivatives of phosphine analogs thereof in a polar solvent to obtain pergolide; or the steps of reacting 9,10-dihydrolysergol with dimethyl disulfide and trialkyl phosphine, aryl phosphine or the polymeric derivatives of phosphine analogs thereof in a polar solvent to form a methylsulfide intermediate; reacting the methylsulfide intermediate with an acid anhydride at an elevated temperature in the presence of a catalyst to form a diacylated amide intermediate; and reducing the diacylated amide intermediate with a reducing agent in a solvent to obtain pergolide.
    • 本发明涉及一种制备昂热胶的方法,其包括以下步骤:在催化剂存在下,在升高的温度下使9,10-二氢赖氨酸与酸酐反应,形成三酰化产物中间体; 用还原剂在溶剂中还原三酰化产物中间体以形成伯氨基醇中间体; 并使氨基醇中间体与二甲基二硫醚和三烷基膦,芳基膦或其膦类似物的聚合衍生物在极性溶剂中反应,得到百戈来; 或使9,10-二氢赖氨酸与二甲基二硫醚和三烷基膦,芳基膦或其膦类似物的聚合衍生物在极性溶剂中反应以形成甲基硫化物中间体的步骤; 在升高的温度下,在催化剂存在下使甲硫醚中间体与酸酐反应,形成二酰化酰胺中间体; 并用还原剂在溶剂中还原二酰化酰胺中间体以获得百戈来(pergolide)。

    • Compounds of general formula I, ##STR1## wherein R.sup.1 represents hydrogen or alkyl C.sub.1-3,R.sup.2 represents hydrogen, alkyl C.sub.1-6, alkenyl C.sub.3-6 or alkynyl C.sub.3-6,n and m are integers from 1 to 3, provided that n+m=4, andone of X and Y represents CH.sub.2 and the other represents CHR.sup.3, C=CHR.sup.4 or C=NR.sup.5, in whichR.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11, R.sup.12, R.sup.13, R.sup.14, R.sup.15, R.sup.16 and R.sup.17 are as defined in the specification,and their saltsare useful as pharmaceuticals, in particular as central muscarinic acetylcholine receptors. The compounds are therefore useful in the treatment of diseases such as presenile and senile dementia, Huntington's chorea, tardive dyskinesia, hyperkinesia, mania and Tourette Syndrome, and also as analgesic agents for use in the treatment of severe painful conditions such as rheumatism, arthritis, and terminal illness.
