- W2464513791 abstract "Tosyl esters of Indole acetic acid and Naphthalene acetic acid were prepared by treating the acids with p- toluenesulfonyl chloride in the presence of a strong base triethylamine. The synthesized compounds were identified by TLC technique. IR and 1 H-NMR spectral measurements were carried out to characterize and elucidate the structure of the synthesized compounds. Anti microbial activity on the synthesized compounds were studied by Agar well diffusion method. The result shows that the Tosyl esters are potentially active against Bacterial and Fungal strains. Indoleaceticacid-Triethylamine (0.05 mol dm -3 , 25ml) in Acetonitrile were mixed thoroughly with constant stirring and kept overnight at about 30 o C. The solid product obtained was treated with ether. The upper and bottom layers were collected separately and dried over anhydrous Na2SO4. A solid product obtained from top layer was seperated. The bottom layer was completely evaporated in vacuum to get residue. TLC tests on both products using a mixture of methanol-ether as eluent, showed a single spot. The solid product obtained from the top layer (yield 54%) was identified as p- toluenesulfonylindoleacetate and the solid product obtained from the bottom layer (yield 40%) was identified as triethylammonium chloride from FT-IR (KBr) and 1 H (CDCl3) spectral data. The schematic route of synthesis of tosyl esters of acids were given in Scheme 1. The same procedure was adopted for the synthesis of p- toluenesulfonylnapthaleneacetate (yield 60%) Scheme 1" @default.
