반응 단계
Forty-eight milligrams (0.6 mmol) of acetic acid chloride was added to a mixture of 111 milligrams (1.1 mmols) of 3,5-dihydroxycyclopent-1-ene and 0.5 milliliter of pyridine with stirring over a period of 5 hours. The aftertreatment was carried out as in Example 1, and 62 milligrams of a crude product was obtained. When calculations were made from the results of the chromatographic analysis, the yields of the monoacetate and diacetate were 22% and 7%, respectively.
