Procedure

To a solution of 11-benzyloxycarbonyl-8-carbamoyloxymethyl-4-dimethoxymethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-6,9-diyl diacetate (100 mg) in methanol (10 ml) was added 10% palladium on carbon (50 mg). The mixture was stirred for 1 hour under hydrogen atmosphere (20 psi) at ambient temperature. The reaction mixture was filtered through cellulose powder and the filtrate was evaporated in vacuo. The residue was subjected to preparative thin layer chromatography, which was developed with a mixture of chloroform and methanol (10:1, v/v) to afford A-isomer of 8-carbamoyloxymethyl-4-dimethoxymethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-6,9-diyl diacetate (31 mg).
