In this paper, the results obtained in the synthesis of thioamides and ketothioamides by a modification of the WillgerodtKindler reaction, under solventfree and noncatalyst conditions using IR energy as a source of activation, are presented. A microwaveenhanced Kindler thioamide synthesis is introduced. The threecomponent condensations of aldehydes, amines, and elemental sulfur were carried out using 1methyl2pyrrolidone (NMP) as solvent employing microwave flash heating at Synthesis of thioamides WillgerodtKindler Reaction The Willgerodt Reaction allows the synthesis of amides from aryl ketones under the influence of a Lawessons reagent, 28, 29 and the Kindler thioamide synthesis a multicomponent reaction between aldehydes, 3033 ketones 34 or organic synthesis for the preparation of heterocycles containing sulphur [3, 4.
The synthesis of thioamides derivatives has attracted so much attention among many researchers and several synthesis methods have been developed which validated is the WillgerodtKindlers reaction (WK). We reported recently a study which the synthesis by reaction of WillgerodtKindler in acid catalysis with K10 and DMF as solvent of phenyl (morpholino) methanethione and dimethylaminophenyl (morpholino) methanethione was discussed [8.
A onepot synthesis of thiomorpholides 13is introduced. The WillgerodtKindler reaction of The WillgerodtKindler reaction of acetone with sulfur and morpholine gives selectively one of the products 14 depending upon the What Is a Synthesis Essay? Before we jump right into generating ideas and writing your synthesis, it would be pretty useful to know what a synthesis essay actually is, right? When you think about a synthesis essay, you can think of it as being kind of like an argumentative essay.
