Recent advances in the synthesis of 3,4-fused tricyclic indoles
Abstract
The 3,4-fused tricyclic indole framework is a key structural motif in numerous bioactive natural products and pharmaceuticals, thus, it has drawn much attention in synthetic organic chemistry. Synthetic organic chemists have expended substantial effort in developing efficient methods for constructing this privileged molecular framework. In this review, we highlight the advances made in this area, particularly since 2018.
