Abstract
The directed 'ortho' metalation (D' o'M) induced anionic rearrangement of 'N,N'-diaryl ureas 1.203 into 'N'-arylanthranilamides 1.204 and 1.205 (Scheme 1.55/Scheme 1.61) has been studied in detail. A highly regioselective 'N'-anionic 'ortho ' Fries rearrangement of unsymetrical 'N,N'-diaryl ureas has been developed ('Scheme 1.61') and a 'pseudo '-regiospecific version of this rearrangement for the synthesis of 1,2,3-trisubstituted 'N'-arylanthranilamides 1.210 (Scheme 1.58) has also been established. The synthetic utility of this new anionic 'ortho' Fries rearrangement has been demonstrated in the total synthesis of two acridone alkaloid natural products, yukodine 1.215 and junosidine 1.6 (Schemes 1.66 and 1.67) .
