Two Novel 15(10→1)Abeomuurolane Sesquiterpenes from Cosmos sulphureus

Two novel 15(10→1)abeomuurolane sesquiterpenes, cosmosoic acid (1) and cosmosaldehyde (2), were isolated from the whole plant of Cosmos sulfurous. Their structures were established by a combination of 1D‐ and 2D‐NMR spectroscopic techniques. Additionally, a chemical correlation between 1 and 2 was a...
