Reaction Steps
100 mg (0.27 mmol) of penicillide (Ib) are stirred in 2 ml of pyridine and 1 ml of acetic anhydride for 14 h at 25° C. with the exclusion of moisture. The reaction mixture is evaporated in vacuo, the residue is taken up in methylene chloride and the solution is washed with water. The evaporation residue of the dried organic phase is chromatographed on silica gel using hexane/diethyl ether.
