We report a new visible-light-mediated carbonylative amidation of aryl, heteroaryl, and alkyl halides. A tandem catalytic cycle of [Ir(ppy)2(dtb-bpy)]+ generates a potent iridium photoreductant through a second catalytic cycle in the presence of DIPEA, which productively engages aryl bromides, iodides, and even chlorides as well as primary, secondary, and tertiary alkyl iodides. The versatile in situ generated catalyst is compatible with aliphatic and aromatic amines, shows high functional-group tolerance, and enables the late-stage amidation of complex natural products.

A suite of flexible and chemoselective methods for the transition-metal-free oxidation of amides to α-keto amides and α-hydroxy amides is presented. These highly valuable motifs are accessed in good to excellent yields and stereoselectivities with high functional group tolerance. The utility of the method is showcased by the formal synthesis of a potent histone deacetylase inhibitor.

A series of N-substituted morpholines 2-20 was synthesised by reacting various acid chlorides and alkyl halides with morpholine (1). All of the synthesised compounds 2-20 were screened for their leishmanicidal effects using amphotericin B (IC50 = 0.24 μg L-1) and pentamidine (IC50 = 2.56 μg mL-1) as standards and a structure-activity relationship (SAR) study was established. The compounds 2 (IC50 = 48 μg mL-1), 3 (IC50 = 30.0 μg mL-1), 10 (IC50 = 41.0 μg mL-1), 15 (IC50 = 33.0 μg mL-1), 16 (IC50 = 35.0 μg mL-1) and 20 (IC50 = 47.0 μg mL-1) showed weak leishmanicidal activities.
