Chemistry &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
