Kineticresolution of α-furfuryl amide was first carried out by using the modified Sharpless asymmetric epoxidation reagent to give the slow-reacting enantiomers, (S)-1a–f and (R)-1b,f in high enantioselectivity (90–100% e.e) and high chemical yield (45–50%).

Phthalide annulation of 2-alkylpyridin-3-ones results in the formation of the unexpected 2-aza-1-cyano-4-hydroxy-anthraquinones, the cyano moiety originating from the 3-cyanophthalide. These compounds hold great potential against Epstein-Barr Virus Early Antigen (EBV-EA) activation and as antimicrobial compounds
