Treatment with acids converted N-(2-hydroxy-2-Phenethyl)-2-aminomethylthiophens into thienotetrahydro-pyridines in good yield; with trifluoroacetic acid the major product was the rearranged 7-phenyl-4,5,6,7-tetrahydrothieno[3,2-c]pyridine, whereas with polyphosphoric acid the product formed exclusively was the non-rearranged 4- phenyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine.
用酸处理将N-(2-羟基-2-苯乙基)-2-氨基甲基噻吩转化为噻吩四氢吡啶,收率良好。与三氟乙酸反应的主要产物是重排的7-苯基-4,5,6,7-四氢噻吩并[3,2- c ]吡啶,而与多磷酸反应的产物仅是未重排的4-苯基-4, 5,6,7-四氢噻吩并[2,3- c ]吡啶。
