DCJTB(CAS号：200052-70-6)通常如何合成？
答案
![{2-(2-Methyl-2-propanyl)-6-[(E)-2-(1,1,7,7-tetramethyl-2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinolin-9-yl)vinyl]-4H-pyran-4-ylidene}malononitrile](https://cnstatic.chemtradehub.com/structs/200/200052-70-6-0060.webp "{2-(2-Methyl-2-propanyl)-6-[(E)-2-(1,1,7,7-tetramethyl-2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinolin-9-yl)vinyl]-4H-pyran-4-ylidene}malononitrile")
DCJTB通常通过复杂的一锅法合成，首先将2-(2-甲基-2-丙基)-4H-吡喃-4-酮与1,1,7,7-四甲基-2,3,6,7-四氢-1H,5H-吡啶并[3,2,1-ij]喹啉-9-醇进行环加成反应，随后通过烯烃加成反应得到目标产物。该过程中使用了钯催化剂，产率约为70%。
