The present invention is directed to analogs of aminoglycoside compounds of the class having a glycosylated 2-deoxystreptamine (2-DOS) ring as well as their preparation and use as prophylactic or therapeutics against microbial infection. Compounds of the invention comprises at least one aryl, heteroaryl, substituted aryl or substituted heteroaryl group in place of a glycosyl group attached to the 2-deoxystreptamine ring.
A novel and simple transition metal-free direct arylation of arene and N-heteroarenes with diaryliodonium salts has been developed. This cross-coupling reaction is promoted only by base and gives the desired products in moderate to good yields.
