Regioselective Formation of Six- and Seven-Membered Ring by Intramolecular Pd-Catalyzed Amination of <i>N</i>-Allyl-anthranilamides

Abstract

A divergent synthesis of quinazolin-4-ones and 1,4-benzodiazepin-5-ones by Pd(II)-catalyzed intramolecular amination of tosylated N-allyl-anthranilamides is described. Both kinds of products were available in high yields depending on the different reaction conditions.
