Challenging functionalization of C(sp3)-H has recently attracted much attention of organic chemists. In this paper, we developed a Ni(acac)2-catalyzed activation of unreactive alkanes with formanilides in the presence of carbon monoxide to furnish moderate to excellent yields of amides. This is the first example of aminocarbonylation of inert alkanes using nickel-based catalyst, and formanilides is disclosed to be an interesting amine source owing to the peculiar deformylation nature of imide intermediates.

The trifluoroacetic acid (TFA) mediated hydration of ynamides was developed, which is an efficient approach for the synthesis of N-monosubstituted amides. This convenient method is effective with a wide range of substrates under room temperature condition, and the products are obtained in high to excellent yields through an easy work-up process.

A general, catalytic and sustainable synthesis of amides has been targeted which utilises a chemoenzymatic step to generate an activated amide coupling partner in situ. A screen of a series of known activating agents was performed and the successful agents taken forward to determine their utility in such a one-pot enzyme-catalysed process. In these studies, a new chemoselective reagent ((isopropylideneamino) 2-phenylacetate) has been identified, which demonstrates excellent selectivity for the acylation of primary anilines over secondary anilines, unlike the more conventional acid chloride equivalent, which is unselective. The development of a chemoenzymatic synthesis of 2-hydroxyethyl benzoates (ethylene glycol mono-benzoate esters) has also been achieved.

Selective inhibitors of human sirtuin 2 (SIRT2), a deacetylase, are candidate therapeutic agents for neurodegenerative diseases such as Parkinson's disease and Huntington's disease as well as potential tools for elucidating the biological functions of SIRT2. On the basis of homology models of SIRT1 and SIRT2, we designed and prepared a series of 2-anilinobenzamide analogues. Enzyme assays using recombinant SIRT1 and SIRT2 revealed that 3'-phenethyloxy-2- anilinobenzamide analogues such as 33a and 33i are potent and selective SIRT2 inhibitors, showing more than 3.5-fold greater SIRT2-inhibitory activity and more than 35-fold greater SIRT2-selectivity compared with AGK2 (3), a previously reported SIRT2-selective inhibitor. Compound 33a also induced a dose-dependent selective increase of α-tubulin acetylation in human colon cancer HCT116 cells, indicating selective inhibition of SIRT2 in the cells. These 3'-phenethyloxy-2-anilinobenzamide derivatives represent an entry into a new class of SIRT2-selective inhibitors.
