75% | With triethylamine; In tetrahydrofuran; at 20℃; for 4h; | General procedure: Coumarin sulfonates derivatives 4-43 were synthesized byreacting 3-hydroxy coumarin 1, 4-hydroxy coumarin 2 and 6-hydroxy coumarin 3 derivatives (1 mmol) with commercially available sulfonyl chlorides derivatives (1.2 mmol) in THF(15 mL) in the presence of triethyl amine (1 mmol). Reaction mixture was stirred for 4 h at room temperature to afford coumarin sulfonates 4-43. TLC monitoring was used to determine the progressof the reaction. After the completion of reaction, THF was evaporated and then solid product was washed with distilled water and dried under vacuum. The products were crystallized from methanol afforded good yields (Scheme 1). |
