One‐Pot Four‐Component Synthesis of Novel Amino‐Tetrahydro‐Chromene Derivatives Anchored with Dual Triazole Moieties

open access: yesChemistryOpen, EarlyView.
A series of tetrahydrochromene derivatives bearing triazole rings is synthesized via a one‐pot reaction. The process is optimized by ultrasonication of a basic aqueous tert‐butanol mixture. Subsequently, the optimized steps are successfully integrated into a four‐component, one‐pot protocol. The whole process was completed in less than 2 h.

Quality Control Strategies for Differentiation of Kalanchoe Species

open access: yesPhytochemical Analysis, EarlyView.
ABSTRACT Kalanchoe species products are commercially available in local markets and by internationally accessible online retailers and may exhibit quality issues because of misidentification from similar common names and anatomical similarities among related species used as feedstock. This study proposes an approach using UPLC‐MS/MSE and HPTLC, coupled
