class of enamino esters has been isolated in excellent yields from the 1:1:1 addition reaction between phenanthridine or isoquinoline and activated acetylenic esters in the presence of heterocyclic NH compounds (succinimide, 5-nitroindazole, benzoxazolinone, 6-chlorobenzoxazolinone, carbazole and 3,6-dibromocabazole) or 1,3-dicarbonyl compounds such as 1,3-dimethylbarbituric acid and 1,3-diethyl-2-thiobar-
在杂环 NH 化合物(琥珀酰亚胺、5-硝基吲唑、苯并恶唑啉酮、6-氯苯并恶唑啉酮、咔唑)存在下,菲啶或异喹啉与活化炔酸酯之间的 1:1:1 加成反应以优异的产率分离出一类新的烯氨基酯和 3,6-二溴咔唑)或 1,3-二羰基化合物,例如 1,3-二甲基巴比妥酸和 1,3-二乙基-2-硫代巴比妥酸。
