8-Iodo-4-methyl-2-oxo-2H-chromen-7-yl Benzenesulfonate
We report a straightforward and efficient synthesis of 4-methyl-2-oxo-2H-chromen-7-yl benzenesulfonate (3a) and 8-iodo-4-methyl-2-oxo-2H-chromen-7-yl benzenesulfonate (3b) in good yields through an O-sulfonylation reaction of 7-hydroxy-2H-chromen-2-ones 1a and 1b with benzenesulfonyl chloride 2 mediated by triethylamine in dichloromethane at ambient temperature. The aryl sulfonyl esters were characterized using spectroscopic, spectrometric, and thermal analyses.
