The rapid, simple, microwave-promoted synthesis of N-aryl functionalized beta-amino esters using Michael addition reactions is presented. Reactions are performed neat at 200 degrees C for 20 min and are catalyzed by acetic acid. The esters can be easily hydrolyzed to the corresponding N-aryl functionalized beta-amino acids.

Structure-activity relationships have been ascertained and chemical methodology developed for a series of antimalarial 3-chloroindolo[3,2-c]quinoline-5-oxides. The basic side chain as well as the ring N-oxide are critical for antimalarial activity as is a bromine or chlorine in position 3. Substitution at positions 7, 8, 9, 10 is not essential, although the most potent analog in our studies was the 8-nitro compound 4vv.
