実験手順: Phenol 21 in FIG. 40 was synthesized as follows. Anisomycin 19 (0.5 g 1.88 mmol) was suspended in 15 mL of acetonitrile. 9-Fluorenylmethyl succinimide (0.762 g 2.26 mmol) was added to the suspension. Upon addition, all solid dissolved. After stirring for 16 hours at room temperature, water was added to the reaction solution, and it was extracted with ethyl acetate. The organics were combined and dried over sodium sulfate. After filtration and concentration, purification was accomplished by column chromatography using 3:1 hexanes:ethyl acetate as the mobile phase. This gave 9-fluorenylmethyl carbamate 20 as foam in quantitative yields (0.916 g). Upon addition all solid dissolved was extracted with ethyl acetate dried over sodium sulfate After filtration and concentration, purification
