1-苯并呋喃-3-磺酰基 氯化物

反应条件: temp:50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To the above prepared benzofuran-3-sulfonyl chloride (0.104 g, 0.480 mmol) was added ammonia (6 eq., 0.5 M in dioxane) and the mixture stirred for one night at 50° C. Evaporation of the solvent, followed by flash chromatography (SiO2, heptane/AcOEt=7/3) and direct crystallization from heptane/AcOEt, generated 0.036 g of the title compound as off-white crystals. Extensive nOE measurements and 13C-NMR NMR corroborated the structure.
