The synthesis of vabicaserin analogues bearing a quaternary center or spiro substitution at the 4-position has been studied via a [6π]-acrylanilide cyclization employing flow photochemistry in a mesoscale and microfluidic flow photoreactor. The method is also used to synthesize 4,4′-disubstituted tetrahydroquinolines and, furthermore, enables the first synthesis of (±)- trans -vabicaserin.
已经通过 [6π]-丙烯酰苯胺环化在中尺度和微流体流动光反应器中使用流动光化学研究了在 4 位带有四元中心或螺取代的 vabicaserin 类似物的合成。该方法还用于合成 4,4'-二取代的四氢喹啉,此外,还可以首次合成 (±)-反式 -vabicaserin。
