The chemoselective reduction of several structurally diverse compounds containing carbonyl groups was achieved in the presence of low-valenttitaniumreagents. This novel synthetic method provides easy access to highly selective reduction of carbonyl groups, and possesses several advantages including one-step procedure, convenient manipulation, good to excellent yields, and short reaction times.
A simple and efficient method for the synthesis of α-ketothioamides via the Willgerodt–Kindlerreaction is developed. Reactions were carried out between arylglyoxal hydrates, amines and elemental sulfur in water at 80°C to afford corresponding α-ketothioamides in good to high yields in a short reaction time.

Given the putative role of PHGDH in cancer, development of inhibitors is required to explore its function. In this context, we established and validated a straightforward enzymatic assay suitable for high-throughput screening and we identified inhibitors with similar chemical scaffolds. Through a convergent pharmacophore approach, we synthesized α-ketothioamides that exhibit interesting in vitro PHGDH

The Willgerodtreaction under iron-catalyzed aerobic conditions was found to be an excellent tool for full α-heterofunctionalization of acetophenones with sulfur and amines. Via this break-and rebuild strategy, a wide range of thioglyoxamides was synthesized in a four-component, highly atom-, step- and redox-economical manner with water as the only by-product.
