Stereodivergent Photooxidative Synthesis of Cyclocariols A, B, and E from Ginsenoside Rg1 | Synapse

April 10, 2026

Stereodivergent Photooxidative Synthesis of Cyclocariols A, B, and E from Ginsenoside Rg1

Key Points

The aim is to develop a stereodivergent method for synthesizing cyclocariols A, B, and E from ginsenoside Rg1.
Employ visible-light-induced photooxidation
Conduct β-fragmentation/elimination cascade reactions
Focus on the transformation of ginsenoside Rg1 into cyclocariols
Successfully synthesized cyclocariols A, B, and E
Achieved high stereoselectivity in the reactions
Demonstrated the efficiency of visible-light-induced methods for triterpenoid synthesis

Abstract

We report a stereodivergent photooxidative synthesis of the 3,4-seco-dammarane triterpenoids cyclocariols A, B, and E from the commercially available ginsenoside Rg1. This study features a visible-light-induced β-fragmentation/elimination cascade reaction that...
