AbstractSimplest derivatives of the cotarnine alkaloid, like cotarnone and 1,2-dihydrocotarnine, undergo electrophilic Einhorn acylamidomethylation (with 60–95% yield) and sulfochlorination with chlorosulfonic acid at position 5. At the same time cotarnone and its derivatives undergo additional O-protodemethylation. Using these and some other reactions, we synthesized a number of previously unknown
摘要cotarnine生物碱的最简单衍生物,如cotarnone和1,2-二氢cotarnine,在位置5进行亲电的Einhorn乙酰氨基甲基化(收率60–95%)并用氯磺酸进行磺氯化反应。同时,cotarnone及其衍生物进行额外的O-原脱甲基化反应。使用这些反应和其他一些反应,我们合成了具有5-氯乙酰氨基甲基,5-芳基氨基甲基,5-氨基甲基和5-磺酰胺基团的两种底物的许多先前未知的衍生物。
