The reaction of thioacetamides with dimethylacetylenedicarboxylate affords 3-oxothien-2-ylidene or 4-oxothiazol-2,5-ylidene derivatives based on the structure of the thioacetamides and the solvent employed. The structural features of the 3-oxothien-2-ylidenes are discussed.

Twist and shout: The synthesis of polyfunctional thiophenes is reported. Quantum-mechanical calculations explain the synthetic pathway of this heterocyclization. Both experimental and computational spectral results demonstrate that the optical properties of the synthesized thiophenes are caused by the presence of an intramolecular charge-transfer (ICT) state during absorption and a twisted ICT state

Herein, we describe the synthesis of 4,5-disubstituted-3-trihalomethylisothiazoles from trihaloacetonitriles and 2-cyanothioacetamides or 2-ethoxycarbonylthioacetamides. The reactivity of the necessary trihaloacetonitriles has a significant impact on the observed reaction pathways. Reactions with CF3CN require an oxidant to mediate cyclization, while CCl3CN functions as both the reactant and oxidant. (C) 2009 Elsevier Ltd. All rights reserved.

The reaction between enamines and azaenamines containing a thioamide group and dimethyl acetylenedicarboxylate was studied under various conditions. It was shown that exchanging one of the carbon atoms in the structure of the investigated compounds for a nitrogen atom significantly affected the reactivity. Functionalized thiopyrans and thiazolidinones were obtained during this investigation.
