A series of novel N-benzylidenesulfonohydrazide compounds were designedand synthesized as inhibitors of UDP-N-acetylmuramic acid:L-alanine ligase (MurC) andUDP-N-acetylmuramoyl-L-alanine:D-glutamate ligase (MurD) from E. coli, involved inthe biosynthesis of bacterial cell-walls. Some compounds possessed inhibitory activityagainst both enzymes with IC50 values as low as 30 μM. In addition, a new, one-potsynthesis of amidobenzaldehydes is reported.

Transition‐metal catalyzedC—H functionalization of benzaldehydes is of great interest in organic synthesis. Herein, we developed a transient directing group assisted amidation of benzaldehydes catalyzed by rhodium catalyst. With the employment of 10 mol% of 4‐trifluoromethyl aniline, the in situ generated imine groups as the directing group efficiently enable this transformation. By using this protocol

azides as amidation surrogates under cationic iridium(III) catalysis is described. This transformation efficiently provides a range of 2-aminobenzaldehyde derivatives with excellent site selectivity and functional group compatibility. The resulting 2-aminobenzaldehyde framework provides facile access to a range of biologically interesting heterocycles. In addition, all synthetic compounds were screened
