- 다음의 구조식(Ⅱ)의 화합물을 산의 관능성 유도체를 형성시켜 주는 작용제와 반응시키는 것을 특징으로 하는 구조식(Ⅰ)인 시클로펜탄올의 락톤 유도체의 제조방법.윗 구조식에서; 점선은 제2결합의 존재를 의미하고, A는 단일결합이나, -(CH₂)₂-기를 의미하며, R은 수소, 또는 수소 탄소수가 1-4인 포화 혹은 불포화 알킬기를 나타내고, R1은OR1기를 나타내는데, 여기에서 R1는 수소, 테트라하이드로 피라닐기, 탄소수 1-3인 알킬기, 또는 COR"기를 의미하며 이때의 R"는 카복실기에 의해 임의로 치환된 탄소수 1-3의 알킬기이나 페닐기이다.R과 R1은 함께 케톤 그룹을 이루기도 하며, R2는-(CH₂)m-CH3기를 나타내는데 여기에서 mA는 3,4 또는 5인 정수이다.파상선은 그 결합이 하나, 또는 그 이상의 가능한 입체배치중의 한쪽 또는 다른쪽에 있을 수 있음을 의미한다. A가 단일결합인 경우 펜탄고리와 산소사이의 결합은 α결합이다.
