Bioorg Med Chem 2014; 22:3749-52.

Abstract
A productive synthesis of benzo[a]phenoxazine derivative SSJ-183 (1), a promising lead for antimalarial agents, was developed using a one pot procedure. Furthermore, N-deethylated metabolite 3 and bis-N,N-deethylated metabolite 4 were synthesized by the application of the method. The metabolites 3 and 4 showed comparable and ∼2-fold increased activities against drug-sensitive and drug-resistant Plasmodium falciparum parasites.
