2-Thioxo-4,6-diphenyl-1,2-dihydronicotinonitrile has been prepared via condensation of benzaldehyde with cyanothioacetamide and N-(1-styryl)morpholine; alkylation of the product with alkyl halides has afforded substituted 2-alkylsulfanyl-4,6-diphenylnicotinonitriles and 3-amino-2-acyl-4,6-diphenylthieno[2,3-b]pyridines.
通过苯甲醛与氰基硫代乙酰胺和N-(1-苯乙烯基)吗啉的缩合反应制得2-硫代-4,6-二苯基-1,2-二氢噻吩腈。用卤代烷烷基化产物,得到取代的2-烷基硫烷基-4,6-二苯基烟腈和3-氨基-2-酰基-4,6-二苯基噻吩并[2,3- b ]吡啶。
