As a part of a search for novel biological active ergoline derivatives, the indole ring present in the ergoline skeleton (indole[4,3-f,g]quinoline) was converted into different heterocyclic ring systems such as quinazoline 2, benzofurane 3 and benzoxazole 4. Due to the paramount importance of chirality to attain biological activity, natural dihydrolysergic acid 1 was chosen as starting material and
作为寻找新型生物活性麦角灵衍生物的一部分,麦角灵骨架(吲哚[4,3- f,g ]喹啉)中存在的吲哚环被转化为不同的杂环系统,例如喹唑啉2,苯并呋喃3和苯并恶唑4。由于手性对于获得生物活性至关重要,因此选择天然的二氢麦角酸1作为起始原料,并遵循手性方面保守的合成途径。
