Leveraging Isomerization of Azo Dyes and Imines for the Facile Synthesis of Oxadiazepines and Related Heterocycles

Journal of Heterocyclic Chemistry, EarlyView.
A robust method for synthesizing substituted oxadiazepines and related heterocycles via intramolecular SNAr is detailed. Under mild conditions, this methodology has been leveraged to afford products of varying electronic and aryl nature in up to 99% yields.

Unveiling chemical composition of peppermint oil and its bioactivities compared with (R)‐(+)‐limonene: antimicrobial, antibiofilm, and insecticidal perspectives

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Peppermint (Mentha piperita L.) essential oil (MPEO) is recognized for its broad‐spectrum antimicrobial properties and potential applications in food preservation. This study aimed to determine whether the bioactivity of MPEO is attributable to (R)‐(+)‐limonene or whether the complete essential oil provides higher efficacy due to ...
