4-[3-(3-vinyl-1-acetyl-4-piperidyl)-1-propenyl]-6-methoxyquinoline, the corresponding epoxide and related compounds, useful in the synthesis of Cinchona alkaloids, are prepared by introducing an ylid group in the 4-position of a suitably substituted quinoline and reacting this ylid with an N-acetyl-4-piperidineacetaldehyde.
4-[3-(3-乙烯基-1-乙酰基-4-哌啶基)-1-丙烯基]-6-甲氧基喹啉,对应的环氧化物和相关化合物,可用于合成奎宁生物碱,通过在适当取代的喹啉的4位引入一个ylid基团,并将该ylid与N-乙酰-4-哌啶乙醛反应来制备。
