Furopyridones 4a-c were shown to be available as synthons for alkaloid synthesis by their facile conversion to the key intermediates 13a, b, and 16 for the synthesis of quinine, ajmalicine, and 7-demethyltecomanine.
Furopyridones 4a-c 被证明可以作为生物碱合成的合成基体,通过其简单转化为关键中间体 13a、b 和 16,进而用于奎宁、阿片碱和 7-去甲基特可曼宁的合成。
