摘要
A new 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-diethy1-2-thiobar- bituric acid.
