Biogenetic-like one-step construction of the pentacyclic aminal core of zoanthamine/norzoanthamine alkaloids was accomplished in high yield from the suitably protected monocyclic aminohydroxy diketocarboxylic acid 7 by heating in aqueous acetic acid.
通过在乙酸水溶液中加热,由适当保护的单环氨基羟基二酮基羧酸7以高收率完成了邻氨基苯乙胺/去甲氨基苯乙胺生物碱的五环氨基环戊二烯类生物核心的一步生物构建。
