보다 상세하게는, 본 발명은 삼중결합을 가지는 아미노알킨 유도체를 분자내 하이드로아미네이션(intermolecular hydroamination)시켜 고리형 이민 화합물을 제조하는 반응에서 우수한 활성을 보이는 타이타늄-아미노 금속화합물과, 4B족 금속 양이온과 특정의 음이온 리간드가 화학결합을 이루고 있는 4B족 금속착물과, 4B족 금속화합물과 특정의 리간드를 포함하는 촉매 조성물을 촉매로 사용하는 용도에 관한 발명과, 상기한 촉매를 사용하여 삼중결합을 가지는 아미노알킨 유도체를 분자내 하이드로아미네이션(intermolecular hydroamination)시켜 하기 화학식 1로 표시되는 고리형 이민 화합물을 제조하는 방법에 관한 발명이다.More specifically, the present invention provides a titanium-amino metal compound and a Group 4B metal cation which exhibit excellent activity in the reaction of preparing an cyclic imine compound by intramolecular hydroamination of an aminoalkyne derivative having a triple bond. The invention relates to the use of a catalyst composition comprising a Group 4B metal complex having a chemical bond with a specific anionic ligand, a Group 4B metal compound and a specific ligand as a catalyst, and a triple bond using the catalyst described above. The present invention relates to a method for preparing a cyclic imine compound represented by the following Chemical Formula 1 by intramolecular hydroamination of an aminoalkyne derivative.
상기 화학식 1에서, R1, R2, 및 R3은 서로 같거나 다른 것으로서 수소원자, C1∼C6의 직쇄 또는 분쇄형 알킬기, 벤질기, 또는 벤질옥시기를 나타내고; R4는 수소원자, C1∼C6의 직쇄 또는 분쇄형 알킬기, 또는 페닐기를 나타내고; n은 1 내지 3의 정수이다. In Formula 1, R 1 , R 2 , and R 3 are the same as or different from each other, and represent a hydrogen atom, a C 1 to C 6 straight or crushed alkyl group, benzyl group, or benzyloxy group; R 4 represents a hydrogen atom, a C 1 to C 6 straight or branched alkyl group, or a phenyl group; n is an integer of 1-3.
아미노알킨(aminoalkyne)의 분자내 하이드로아미네이션(intermolecular hydroamination)을 수행하여 질소를 포함한 고리 화합물을 합성하는 반응에서, 전이금속(transition metal)이 촉매활성을 나타냄에 대해서는 이미 잘 알려져 있다. [Chem. Rev. 1998, 98, 675; Organometallics 2000, 19, 87; Organometallics 2000, 19, 170; Organometallics 2000, 19, 539; J. Am. Chem. Soc. 2000, 122, 9546; Org. Lett. 2000, 2, 1935; J. Am. Chem. Soc. 2001, 123, 2923; Chem. Soc. Rev. 2003, 32, 104; Eur. J. Org. Chem. 2003, 935; Chem. Rev. 2004, 104, 3079] 또한, 전이금속 촉매로서 메탈로센 (metallocene) 촉매들은 대부분이 공기 중이나 수분에 노출되었을 때, 촉매의 활성이 매우 저해된다는 것과 촉매의 다양성 측 면에서 한계점을 지니고 있음에 대해서도 잘 알려져 있다. [Angew. Chem. Int. Ed. 2004, 43, 5542] 그리고, 4B족 전이금속 중에서도 지르코늄만이 분자내 하이드로아미네이션 반응에서 촉매활성이 극대화되므로 4B족 금속은 지르코늄 금속촉매로 제한되며, 그 촉매의 활성은 2차 아미노알켄(aminoalkene) 기질에만 적용되는 단점이 있음에 대해서도 잘 알려져 있다. 따라서 분자내 하이드로아미네이션 반응에 의하여 알칼로이드와 같은 질소를 포함한 고리 화합물을 합성하는 분야에서는, 활성을 극대화할 수 있는 촉매의 개발이 절실히 요구되고 있다.It is well known that transition metals exhibit catalytic activity in the reaction of synthesizing nitrogen-containing ring compounds by performing intramolecular hydroamination of aminoalkyne. Chem. Rev. 1998 , 98 , 675; Organometallics 2000 , 19 , 87; Organometallics 2000 , 19 , 170; Organometallics 2000 , 19 , 539; J. Am. Chem. Soc . 2000 , 122 , 9546; Org. Lett . 2000 , 2 , 1935; J. Am. Chem. Soc . 2001 , 123 , 2923; Chem . Soc . Rev. 2003 , 32 , 104; Eur . J. Org . Chem . 2003 , 935; Chem . Rev. 2004 , 104 , 3079] In addition, most of metallocene catalysts as transition metal catalysts have limitations in that the activity of the catalyst is very impaired when exposed to air or moisture and the diversity of the catalyst. It is well known. Angew. Chem. Int. Ed . 2004 , 43 , 5542] Among the 4B transition metals, only zirconium maximizes the catalytic activity in the intramolecular hydroamination reaction, and therefore, the 4B metal is limited to the zirconium metal catalyst, and the activity of the catalyst is secondary aminoalkene. It is also well known that there are disadvantages that apply only to substrates. Therefore, in the field of synthesizing ring compounds containing nitrogen such as alkaloids by intramolecular hydroamination reaction, the development of a catalyst that can maximize the activity is urgently required.
이에 본 발명에서는 메탈로센 촉매보다 상대적으로 안정한 넌-메탈로센 (non-metallocene) 계열의 4B족 금속을 사용하고, 복잡한 구조의 리간드 보다는 합성이 용이한 특정 구조의 리간드를 선택하되, 아미노알킨 유도체를 기질로 사용하여 고리형 이민 화합물을 합성하기 위한 분자내 하이드로아미네이션 반응에서 우수한 촉매활성을 나타내는 신규 촉매를 개발하였다.Therefore, in the present invention, a non-metallocene-based group 4B metal, which is relatively more stable than a metallocene catalyst, is used, and a ligand having a specific structure that is easy to synthesize is selected, rather than a complex ligand, and an aminoalkyne. Using a derivative as a substrate, a novel catalyst has been developed that exhibits excellent catalytic activity in the intramolecular hydroamination reaction to synthesize cyclic imine compounds.

상기 배경기술에서 이미 설명한 바와 같이, 4B족 금속화합물로서 지르코늄 화합물만이 제한적으로 분자내 하이드로아미네이션 반응에서 활성을 나타내는 것으로 현재까지 보고되어 있다. 그러나, 본 발명이 제안하는 상기 화학식 2로 표시되는 타이타늄-아미노 화합물은 타이타늄 금속 양이온과 화학결합을 이루는 음이온이 Clp(NR2)q으로 특정됨으로써 분자내 하이드로아미네이션 반응에서 우수한 촉매활성을 나타낸다. 따라서, 본 발명은 분자내 하이드로아미네이션 반응용 촉매로서 사용 가능한 4B족 금속의 선택 범위를 확대시키는 효과가 있다.As already described in the background art, only zirconium compounds as Group 4B metal compounds have been reported to present their activity in the intramolecular hydroamination reaction to a limited extent. However, the titanium-amino compound represented by the formula (2) proposed by the present invention exhibits excellent catalytic activity in the intramolecular hydroamination reaction by specifying Cl p (NR 2 ) q as an anion forming a chemical bond with a titanium metal cation. . Therefore, the present invention has the effect of expanding the selection range of the Group 4B metals that can be used as the catalyst for intramolecular hydroamination reaction.

The Group 4B metal complexes or catalyst compositions described above are used in intramolecular hydroamination reactions of aminoalkyne derivatives, respectively, and exhibit excellent catalytic activity.

본 발명에 따른 촉매는 기존에 알려진 넌-메탈로센(non-metallocene) 촉매에 비교하여 리간드의 구조가 간단하여 합성이 용이하다.The catalyst according to the present invention has a simple structure of the ligand compared to the conventionally known non-metallocene catalyst and thus is easy to synthesize.
특히 본 발명에 따른 촉매는 리간드의 구조적 특징으로 인하여 4B족 금속의 선택범위를 확대시킬 수 있음은 물론이고, 분자내 하이드로아미네이션 반응에 적용이 용이하지 않았던 다양한 종류의 아미노알킨 유도체를 기질로서 적용하는 것이 가능하다. 이로써 다양한 구조의 고리형 이민 화합물의 합성이 가능해졌다.In particular, the catalyst according to the present invention can broaden the selection range of the Group 4B metal due to the structural characteristics of the ligand, and apply various kinds of aminoalkyne derivatives, which were not easy to apply to intramolecular hydroamination reactions, as substrates. It is possible to. This enabled the synthesis of cyclic imine compounds of various structures.
또한 이렇게 만들어진 고리 이민 화합물은 생화학적 기본구조 물질인 알칼로이드의 전구체로 사용될 수 있다.In addition, the ring imine compound thus prepared may be used as a precursor of an alkaloid which is a biochemical basic material.
