새로운 니트로알켄 타입의 화합물을 합성하기 위하여는 반응식 1 과 같이 우선 방향족 알데하이드에 염기 촉매를 사용하여 중간체인 니트로알콜을 만든 후 축합과정을 통하여 컨쥬게이션된 니트로알켄이 생성된다.In order to synthesize a new nitroalkene type compound, as shown in Scheme 1, a nitroalcohol, an intermediate, is prepared using a base catalyst on an aromatic aldehyde, and then a condensed nitroalkene is produced through condensation.
이 때 사용되는 시약으로는 수산화나트륨(Organic syntheses, Coll Vol. 1,pp. 413-414), 암모니움 아세테이트(Tetrahedron Letters, Vol. 38, No. 29, pp. 5131-5134, 1997) 등이 사용되어진다. 또한 사용되어 지는 방법은 벤젠링에 치환된 물질에 따라서 제한적으로 반응이 진행되어지기 때문에 여러 가지 유도체를 만들기에는 많은 한계점이 있다. 따라서, 본 발명은 이러한 한계점을 극복하여 어떠한 치환체를 가지고 있는 물질이라도 쉽게 합성할 수 있기 때문에 신약개발에서 유용하게 사용가능한 다양한 컨쥬게이션이 된β-니트로 스틸렌 유도체를 합성하는 것이다.Reagents used in this case include sodium hydroxide (Organic syntheses, Coll Vol. 1, pp. 413-414), ammonium acetate (Tetrahedron Letters, Vol. 38, No. 29, pp. 5131-5134, 1997), and the like. It is used. In addition, the method used has a number of limitations in making various derivatives because the reaction proceeds in a limited manner depending on the substance substituted in the benzene ring. Therefore, the present invention overcomes these limitations and can easily synthesize a substance having any substituent, thereby synthesizing β -nitro styrene derivatives having various conjugated properties that can be usefully used in drug development.
