Fused heterocycles, such as benzo[b]thiophene, thiochroman, benzo[b][1,4]thiazine, and 1,4-benzothiazepine were generated from thio-Ugi adducts containing a thioamide group through copper-catalyzed intramolecular C-S bond formation under microwave irradiation.

Amidinium dithiocarbamates salts with diverse structures are prepared in situ by adding one equivalent of CS2 to an equimolar mixture of two nonionic molecules, an amidine and an amine. Many of the salts made in this way are room temperature ionic liquids (RTILs) and the others (ILs) melt well below the decomposition temperature of the salts, ca. 80 °C. Unlike the analogous amidinium carbamate RTILs, which are made by adding CO2 to amidine/amine mixtures and decompose near 50 °C, the amidinium dithiocarbamates do not revert to their amidine/amine mixtures when they are heated. The thermal, rheological, conductance, and spectroscopic properties of representative examples from a total of 50 of these ILs and RTILs are reported, comparisons between them and their nonionic phases (as well as with their amidinium carbamates analogues) are made, and the thermolysis pathways of the ammonium dithiocarbamates are investigated.
Thio FCMA intermediates as strong acyl donors: A general solution to the formation of complex amide bonds
Rao, Yu,Li, Xuechen,Danishefsky, Samuel J.
supporting information; experimental part, p. 12924 - 12926 (2009/12/07)
(Chemical Equation Presented) Novel methodology for the formation of amide bonds under neutral conditions is described. Evidence is presented that the active acyl donors are thio FCMA intermediates, generated from the reactions of thioacids with isonitril
