- 論文の詳細を見る
Reaction of 2-methyl-3-aminoisocarbostyril (I) with benzaldehyde gave the corresponding Schiff base, 2-methyl-3-benzalaminoisocarbostyril (II) and 6,8-dimethyl-14-phenyl-5,6,8,9-tetrahydropyrido[2,3-c ; 6,5-c']diisoquinoline-5,9-dione. (Va) in 23% and 58% yield, respectively. This pyridodiisoquinoline (Va), which was a novel pentacyclic ring system containing three nitrogen atoms, could be synthesized by another route.
