The optically active 1-amino-3-thiaindoloquinolizidine 8 was synthesized by rearrangement of the β-carboline 6 which was obtained by the Bischler-Napieralski reaction of the thioamide 4b followed by NaBH4 reduction, whereas the isomer 7 gave the pentacycle 9.
通过重排β-咔啉6合成旋光的1-氨基-3-噻吩并喹唑啉8,该β-咔啉是通过硫代酰胺4b的Bischler-Napieralski反应,然后用NaBH 4还原而得到的,而异构体7得到的是五环9。
