Abstract: 본 발명은 키랄 알콜을 동적 속도론적으로 분할하는 방법에 관한 것으로서, 구체적으로는 하기 화학식 1의 아미노시클로펜타디에닐 루테늄을 금속 촉매로 사용하여 키랄 알콜을 효소 촉매, 아실 주게 물질, 첨가제 및 염기의 존재 하에 용매 중에서 반응시켜 각각의 에난티오머로 분할하는 방법에 관한 것이다. 본 발명에 따르면 낮은 온도에서 반응이 가능하고 알케닐 아세테이트를 아실 주게 물질로 사용가능하며, 따라서 적은 량의 아실 주게 물질 및 효소를 사용하여서도 생성물의 분리가 용이하므로 공업적, 경제적으로 훨씬 유리하고 수소매개체로서의 케톤을 사용하지 않는 등의 장점이 있다.
