Total Synthesis of rac‐Keramamine C Enabled by Intrinsic H‐Bond‐Induced Conformational Fixation of Amides

European Journal of Organic Chemistry, EarlyView.
The total synthesis of the manzamine alkaloid keramamine C (2) in its racemic form was achieved in 5 steps, with ring‐closing metathesis as the key step. The metathesis is strongly improved by an intramolecular H‐bond‐induced conformational fixation of the amide bond, inducing close proximity of the terminal double bonds in the precursor molecule.

Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

Flavour and Fragrance Journal, EarlyView.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.
