The synthesis of several N-6 derivatives of elymoclavine (3) and potential alkylating derivatives of 6-methyl-8-aminoergolines (12) is described. These compounds were screened for prolactin-inhibiting ability and 6-propyl-8-hydroxymethyl-8-ergolene (9) was found to be as active as the most potent prolactin inhibitors reported to date. The total synthesis of racemic methyl dihydrolysergate I (23), having a trans C, D ring fusion, from the tricyclic ketone 18 is also described.
描述了几种麦角隐亭(3)的N-6衍生物以及6-甲基-8-氨基麦角灵(12)潜在的烷基化衍生物的合成。对这些化合物进行了催乳素抑制能力筛选,发现6-丙基-8-羟甲基-8-麦角烯(9)与迄今为止报道的最有效的催乳素抑制剂活性相当。还描述了由三环酮18全合成具有反式C、D环稠合的外消旋甲基二氢麦角酸酰胺I(23)。
