A Unified Approach to trans-Hydrindane Sesterterpenoids
摘要:
A synthetic approach to several sesterterpenoids containing an isopropyl trans-hydrindane system is presented. Its most remarkable feature is the stereochemical diversification of a common precursor through the choice of different hydrogenation conditions.

Nitidasin is a pentacyclic sesterterpenoid with a rare 5‐8‐6‐5 carbon skeleton that was isolated from the Peruvian folk medicine “Hercampuri”. It belongs to a small class of sesterterpenoids that feature an isopropyl trans‐hydrindane moiety fused to a variety of other ring systems. As a first installment of our general approach toward these natural products, we report the total synthesis of the title
