several novel, so far undescribed 3,4,6-trisubstituted quinoline derivatives. They all bear substituents which are well-suited for further transformations, e.g. carboxylic acid or ester functions, halogens, terminal alkynes and hydroxyl groups. The synthesis of a highly active 3,4-disubstituted quinolin-6-yloxyacetamide fungicide gives proof of the manifold manipulations which are possible with these interesting
Gould-Jacobs环化使得能够合成几种新颖的,迄今未描述的3,4,6-三取代喹啉衍生物。它们均带有非常适合进一步转化的取代基,例如羧酸或酯官能团,卤素,末端炔烃和羟基。高活性的3,4-二取代的喹啉-6-基氧基乙酰胺类杀菌剂的合成证明了这些有趣的杂环双环砌块可能进行的多种操作。
