実験手順

The same procedure was used for the synthesis of the 3-propionyl derivative 4.47 (FIG. 6A). 2,5,6-Trichloro-1-(5-O-acetyl-β-D-ribofuranosyl)indole (4.39, FIG. 6A) was acylated under Friedel-Crafts conditions with propionyl chloride and deprotected in two steps to yield the desired 2,5,6-trichloro-3-propionyl-1-(β-D-ribofuranosyl)indole (4.47, FIG. 6A).
