A chemoselective hydroxymethylation: new route for the synthesis of 6-aroyl-4-(4H-triazol-3-yl)thiomorpholin-3-ones
摘要:
Treatment of 2-(2-oxo-2-arylethylthio)-N-(4H-1,2,4-triazol-3-yl)acetamides with paraformaldehyde in the presence of a base has led to a tandem chemoselective hydroxymethylation followed by cyclization yielding a set of novel 6-aroyl-4-(4H-triazol-3-yl)thiomorpholin-3-ones. The thiomorpholine ring has been found to have a boat like conformation in these compounds as evidenced by NOESY NMR spectrum. (C) 2011 Elsevier Ltd. All rights reserved.
The article summarizes the synthesis of two heterocycles linked by sulfur atom. The Friedlander reactions of 2‐aminoarylketones with ketones 1, 4, and 7 have been explored, and three series of quinolines (3, 5, and 8) have been synthesized.

Synthesis of Biologically Important<i>N</i>-Heteroaryl-2-(heteroarylthio)acetamides
The synthesis of compounds having triazole and selena/thiadiazole rings connected by a chain having sulfur and nitrogen in the link has been described. The resultant N‐heteroaryl‐2‐(heteroarylthio)acetamide may be biologically important as related compounds found application in the inhibition of HIV 1 replications.
