The presence of (E)-5-methylhept-2-en-4-one (®lbertone) in a hazelnut oil, deodorised in a laboratory system using nitrogen as stripping gas, is studied regarding its usefulness as a chiral marker for detecting adulterations of olive oil. The analytical method involves the use of both simultaneous d
## Abstract 1‐Phenylpentane‐1, 4‐diones, and (E)‐5‐hydroxy‐5‐phenylpent‐3‐en‐2‐ones were synthesized via organophosphine‐catalyzed addition reaction of but‐3‐en‐2‐one with aldehydes. The features of the present protocols include high selectivity, operational simplicity, atom economy, and mild react
