実験手順
To a solution of 11-acetyl-6,9-dihydroxy-8-hydroxymethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-triene-4-carbaldehyde (18 mg) in dimethylformamide (1.0 ml) was added a mixture of phenyl isocyanate (12.5 μl) in dimethylformamide (1.25 ml) in an ice-water bath. The mixture was stirred for 30 minutes in an ice-water bath and then stirred for additional 1 hour at ambient temperature. The mixture was evaporated in vacuo and subjected to preparative thin layer chromotography, which was developed with a mixture of chloroform and methanol (15:1, v/v) to afford 11-acetyl-4-formyl-9-hydroxy-6-(N-phenylcarbamoyloxy)-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-8-ylmethyl N-phenylcarbamate (12 mg).
