Alkaloid Synthesis

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.

Cyclic Enaminones

Among many other strategies, the enaminone approach is an important strategy to construct and diversify the azacyclic core in various alkaloids syntheses. In this brief review we discuss the application of cyclic enaminones as building blocks, as well as potential intermediates in the total synthesis of selected alkaloids.
