  1. 1
    AutreThe solvent was removed from the reaction mixture under reduced pressure
  2. 2
    Autreto give a crude oil
  3. 3
    AutreThis oil was purified on silica gel thin layer chromatography (developing solvent: diethyl ether and hexane, 2:1 v/v)

Mode opératoire

To a solution of the FR-900506 substance (9.7 mg) in dichloromethane (0.2 ml) and pyridine (0.1 ml) was added benzoyl chloride (50 μl) at room temperature, and the mixture was stirred at room temperature for 2 hours. The solvent was removed from the reaction mixture under reduced pressure to give a crude oil. This oil was purified on silica gel thin layer chromatography (developing solvent: diethyl ether and hexane, 2:1 v/v) to afford 17-allyl-12-[2-(4-benzoyloxy-3-methoxycyclohexyl)-1-methyvinyl]-1,14-dihydroxy-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1.04,9 ]octacos-18-ene-2,3,10,16-tetraone (8.0 mg).
