Abstract

A general alkyllithium/LDA-mediated rearrangement of N-carbamoyl diarylamines 7a−g into the anthranilamides 8a−g and 9a−g (Table 1) is presented and applied to a regioselective efficient construction of acridone (17) and pyranoacridone (18) alkaloids (Scheme 4). ... Recent efforts in our laboratories aim to develop new carbanionic aromatic chemistry which, by moderating the harsh conditions and circumventing rules of classical electrophilic substitution, offer ...
