Total Syntheses of Agelamadin F and (±)‐Tauroacidin A, Enabled by NaClO2‐Mediated Coupling Reactions of Oroidin and Amines

open access: yesChemistry – A European Journal, EarlyView.
Total syntheses of agelamadin F and (±)‐tauroacidin A were achieved by sodium chlorite (NaClO2)‐mediated oxidative C─N coupling. Nine C15–N–amino acid‐substituted oroidin derivatives were successfully prepared to demonstrate the applicability and versatility of this oxidative coupling reaction.

Inherited metabolic epilepsies–established diseases, new approaches

open access: yesEpilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.
