Synthetic Approaches to α‐, β‐, γ‐, and δ‐Lycoranes

Abstract

AbstractLycorane is a pentacyclic core presented in alkaloids isolated from the Amaryllidaceae family of herbaceous flowering plants. Members of this class of natural products have shown to display important biological properties including analgesic, antiviral, and antiproliferative activities. This review presents the known synthetic routes toward α‐, β‐, γ‐, and δ‐lycoranes. α‐(19 routes), β‐(10 routes), γ‐(38 routes), and δ‐(6 routes).
