We have developed a practical, general protocol for denitration of readily available α-nitroketones with sulfur and amines to access a broad range of α-ketothioamides under mild conditions. Such a reaction proceeds under metal-, oxidant-, and catalyst-free conditions to provide synthetically useful α-ketothioamides. Furthermore, the mild reaction conditions tolerate a wide range of substrates especially for the synthesis of aliphatic α-ketothioamides which are rarely reported.

The Willgerodt reaction 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 synthesi

A domino reaction that involves the formation of CS and C-N bonds in one process via sp3 C-H functionalization strategy has been developed. This reaction affords an efficient and direct method for the synthesis of α-ketothioamides from aryl met

The task of this paper is to provide an efficient process for synthesis of secondary and tertiary α-ketothioamides via Willgerodt-Kindler reaction of readily available arylglyoxals with amines using Na2S as an effective catalyst. A plausible role for Na2S in the reaction of arylglyoxals with primary amines is proposed.

The 1,5-diketone, diphenacylaniline, yielded an enamine under Gewald conditions, while another 1,5-diketone, diphenacyl sulfide, resulted in thioamide formation under identical conditions. 2-Amino-4-(3-oxo-1,3- diphenylpropyl)-4,5,6,7-tetrahydrobenzo[b]th

Willgerodt-Kindler reaction of arylglyoxal hydrates with secondary amines and elemental sulfur under solvent-free conditions at 80 °C is developed, in which α-ketothioamides are obtained in 70-90% yield in 0.6-1 hour. The X-ray crystal-structure analysis for one compound was obtained. Georg Thieme Verlag Stuttgart . New York.
A facile aerobic copper-catalyzed α-oxygenation of aryl thioacetamides: An efficient access to α-keto aryl thioamides

Copper(II) efficiently catalyzes the aerobic oxidation of aryl thioacetamides into the corresponding α-keto aryl thioamides in moderate to high yields in the presence of K2CO3 under O 2 atmosphere. This protocol is simple, clean, and generates water as the only byproduct. A mechanism is proposed for the reaction course. Georg Thieme Verlag Stuttgart.
