PROCEDURE

实验过程

To a stirred solution of the FR-900506 substance (248 mg) in pyridine (7 ml) were added succinic anhydride (145 mg) and 4-(N,N-dimethylamino)pyridine (7 mg), and the resulting mixture was stirred at room temperature for 18 hours. The react on mixture was concentrated under reduced pressure and the residue was subjected to chromatography on silica gel (20 g) with ethyl acetate to give 17-allyl-12-[2-[4-(3-carboxypropionyloxy)-3-methoxycyclohexyl]-1-methylvinyl]-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 (90 mg).
