Abstract: Hexahydro-1H-indol-3-one can be used as a building
block for alkaloid synthesis. Radical and anionic cyclization approaches
toward this useful structure were developed. Approaches toward total
synthesis of montanine-type Amaryllidaceae alkaloids using hexahydro-1H-indol-3-one
as a key intermediate were studied.
