実験手順
To a mixture of 6-hydroxy-5-methoxy-4-[2-methyl-3-(3-methyl-2-butenyl)oxiranyl]-1-oxaspiro[2,5]octane (9.2 g) and pyridine (10.3 g) in dichloromethane (92 ml) was added portionwise 4-nitrophenyl chloroformate (13.1 g) at ambient temperature. After stirring for 3 hours, 5-methoxy-4-[2-methyl-3-(3-methyl-2-butenyl)oxiranyl]-6-(4-nitrophenoxycarbonyloxy)-1-oxaspiro[2,5]octane was prepared in the reaction mixture. To the mixture morpholine (28.4 g) was added in one portion. The solution was stirred for 8 hours at ambient temperature and then diluted with diethyl ether (300 ml). The solution was washed with brine, 1N aqueous hydrochloric acid, 1N aqueous sodium hydroxide and brine successively. The solvent was dried and evaporated in vacuo to give -methoxy-4-[2-methyl-3-(3-methyl-2-butenyl)oxiranyl]-6-morpholinocarbonyloxy-1-oxaspiro[2,5]octane (13.1 g) as an oil.
