A solvent-free and efficient synthesis of bicyclic 2-pyridone derivatives for endoplasmic reticulum imaging

A solvent-free method was developed for the synthesis of bicyclic 2-pyridone (DHIP) derivatives, which demonstrated excellent endoplasmic reticulum (ER) targeting and antibacterial activity after a slight structure regulation.

Organocatalytic diastereoselective [3+2] cyclization of MBH carbonates with dinucleophiles: synthesis of bicyclic imidazoline derivatives that inhibit MDM2–p53 interaction

MBH carbonates were successfully applied to a stereoselective [3+3] annulation with N,C-dinucleophiles for the first time, yielding a collection of pharmacologically interesting bicyclic imidazolines which were found to inhibit MDM2–p53 binding.
