Synthesis of Cycloartan‐16β‐ol from 16β 24R‐Epoxy‐Cycloartane and Their Cytotoxicity Evaluation Against Human Cancer Cell Lines

open access: yesChemistry &Biodiversity, Volume 21, Issue 5, May 2024.
Abstract It was found that Argentatins A and B triterpenoids make up approximately 20–30 % of the waste resin produced from the industrial processes to isolate rubber from P. argentatum. We have developed an efficient protocol for synthesizing cycloartane‐16β‐ol derivatives by opening the oxepane ring of argentatin B acetate (2) with BF3‐OEt2. Although
