유기화학에서 아민 화합물은 이민 화합물과 친핵체와의 첨가반응을 통해 합성할 수 있으며, 특히 생화학적 활성을 지닌 아민 화합물을 합성하기 위한 아민 전구체의 개발 방법은 매우 유용하다. 일반적으로 카보닐 화합물과 친핵체와의 첨가반응을 통한 탄소-탄소 결합 방법은 널리 연구되고 활용되고 있지만 상대적으로 이민 화합물을 이용한 첨가반응은 이민의 낮은 반응성 때문에 많이 개발되지 못했다. 이민의 첨가반응으로는 유기금속 시약을 이용한 반응들이 보고 되어지고 있지만 이민 화합물이 쉽게 가수분해 되기 때문에 비양성자성 용매 (aprotic solvent)를 사용해야 하는 제한 점과 수득 률 또한 좋지 않다.In organic chemistry, amine compounds can be synthesized through addition reaction of imine compounds with nucleophiles, and in particular, a method of developing an amine precursor for synthesizing an amine compound having biochemical activity is very useful. In general, carbon-carbon bonding method through addition reaction of carbonyl compound and nucleophile has been widely studied and utilized, but addition reaction using imine compound has not been developed because of low reactivity of imine. Although addition reactions using organometallic reagents have been reported as imine addition reactions, the limitation and yield of using an aprotic solvent are also poor because the imine compounds are easily hydrolyzed.

유기 금속 시약으로 사용되는 인듐 (Indium) 금속은 다른 금속에 비해 공기 중에 안정하며, 독성이 낮은 장점을 지니고 있다. 인듐 (In)과 알릴 할라이드 또는 프로파질 할라이드 유도체와의 반응을 통해 얻어지는 유기 인듐 시약을 인-시츄 (in-situ)로 제조할 수 있으며, 좋은 친핵체로 사용된다. 최근 유기 인듐 시약을 이용한 이민 화합물의 첨가반응에 대한 연구가 활발히 이루어지고 있다. (Tetrahedron Lett . 1992, 33, 5959; Tetrahedron Lett . 1997, 38, 865; Tetrahedron Lett . 2000, 41, 9311; J. Org . Chem . 2001, 66, 7516; Tetrahedron Lett. 2001, 42, 9073; Tetrahedron Lett . 2003, 44, 6755; J. Org . Chem . 2007, 72, 923; Org . Lett . 2008, 10, 1259). 또한 이민화합물이 가수분해되기 쉬운 점을 극복하기 위해 알데히드 유도체와 아민 유도체의 축합반응을 통해 형성된 이민 화합물을 별도의 분리 없이 유기인듐 시약과의 첨가반응을 진행시켜 아민 화합물을 얻는 반응이 연구되고 있다. (Tetrahedron Lett. 2004, 45, 3413; Bull . Korean Chem . Soc . 2007, 28, 139). 특히 아민 화합물 내 1,3-다이엔 치환체를 도입하는 것은 매우 유용한 방법이 될 수 있으며, 생화학적 활성을 지닌 화합물을 합성하는데 중요한 전구체로 사용될 수 있다. 그러나, 상기 화학식 1로 표시되는 1,3-부타다이엔-2-일 메틸 아민 화합물은 현재까지 많이 보고되지 않은 화합물로, 이의 제조방법 역시 거의 보고된 바가 없다.Indium metal, which is used as an organometallic reagent, is more stable in air than other metals, and has low toxicity. Organic indium reagents obtained through the reaction of indium (In) with allyl halides or propazyl halide derivatives can be prepared in-situ and used as good nucleophiles. Recently, studies on addition reactions of imine compounds using organic indium reagents have been actively conducted. ( Tetrahedron Lett . 1992 , 33 , 5959; Tetrahedron Lett . 1997 , 38 , 865; Tetrahedron Lett . 2000 , 41 , 9311; J. Org . Chem . 2001 , 66 , 7516; Tetrahedron Lett. 2001 , 42 , 9073; Tetrahedron Lett . 2003 , 44 , 6755; J. Org . Chem . 2007 , 72 , 923; Org . Lett . 2008 , 10 , 1259). In addition, in order to overcome the tendency that the imine compound is easily hydrolyzed, the reaction of obtaining an amine compound by proceeding an addition reaction with an indium reagent without separate separation of the imine compound formed through the condensation reaction between the aldehyde derivative and the amine derivative has been studied. . (Tetrahedron Lett 2004, 45, 3413 ;.. Bull Korean Chem . Soc . 2007 , 28 , 139). In particular, the introduction of 1,3-diene substituents in amine compounds can be a very useful method, and can be used as an important precursor for synthesizing compounds with biochemical activity. However, the 1,3-butadien-2-yl methyl amine compound represented by Chemical Formula 1 is a compound that has not been reported much until now, and its preparation method has also been hardly reported.
