DBU-catalyzed 1,6-addition of quinazolinones and quinolones to para‑quinone methides

We report herein a method for a DBU-catalyzed 1,6-addition reaction of quinazolinones and quinolones with para-quinone methides under mild conditions. A series of diarylmethane compounds functionalized with quinazolinones and quinolones were obtained in 41–95% yield with DBU as catalyst.
