New analogues of 2-[2-substituted-3-(3,4-dichlorobenzylamino)propylamino]quinolin-4-ones, 26a, 26b, 31a-e, 34, 35, 38 and 40, have been synthesized and evaluated against Staphylococcus aureus methionyl-tRNA synthetase. All of the synthesized compounds were less active than the reference compound 2. The compounds were also screened against various strains of S. aureus and Enterococci for their antibacterial activities. Among the compounds, 26b, 31c and 31e displayed significant inhibitory properties against various strains of Enterococci compared to compound 2.

High yields of selectively Ar-protected-1,2,3-triaminopropanes (1,3 or 1,2 functionalized diamines) were obtained in 6 or 4 steps from diamino alcohols or aminodiols, respectively. These two multi-step procedures involve protection of the amino group, substitution of the hydroxy group by an azido group and selective reduction. The conditions for the first procedure allow the preparation of various Af2-monoprotected-l,2,3-triaminopropanes 6a, 6b, but the second one is more convenient for obtaining N1-Boc-1,2,3-triaminopropane 6'. These two simplified procedures, which provide functionalized 1,2 or 1,3 diamines easily and with good overall yields, could be useful for the synthesis of : bifunctional chelating agents.
