반응 단계
To a mixture of 1.50 grams (15 mmols) of 3,5-dihydroxycyclopent-1-ene and 1.0 milliliter (120 mmols) of pyridine was added 972 milligrams (9.5 mmols) of acetic anhydride, the addition being made over a period of 7.5 hours with stirring. The aftertreatment was then carried out as in Example 1 to obtain 0.62 gram of a crude product. When calculations were made from the results of the gas chromatographic analysis, the yields of monoacetate and diacetate were 22% and 5%, respectively.
