Under the suitably controlled conditions, the tertiary enaminones undergo intramolecular ring formation at Cα and Cγ to give 1-(2-bromo-4,5-methylenedioxybenzyl) tetra (or hexa)hydro-4(or 6)-oxoindoles which can serve as potential precursors to lycoranes.
在适当控制的条件下,叔烯胺酮在 Cα 和 Cγ 处发生分子内环形成,得到 1-(2-bromo-4,5-methylenedioxybenzyl) 四(或六)氢-4(或 6)-氧代
吲哚,可作为lycoranes 的潜在前体。
