Bischler–Napieralski cyclization of amides synthesized from homoveratrylamine and malonic and succinic acids produced N-(3,4-dimethoxy-β-phenylethyl)-succinimide, 1,1-bis-(6,7-dimethoxy-3,4-dihydroisoquinolin-1-yl)methane, cleavage products, and several intermediates, the structures of which were confirmed using IR and NMR spectral data and x-ray crystal structure analysis.
对由高藜芦胺和丙二酸及琥珀酸合成的酰胺进行 Bischler-Napieralski 环化反应,生成了 N-(3,4-二甲氧基-β-苯基乙基)-丁二酰亚胺、1,1-双-(6,7-二甲氧基-3,4-二氢异喹啉-1-基)甲烷、裂解产物和几种中间体,并利用红外光谱、核磁共振光谱数据和 X 射线晶体结构分析确认了这些中间体的结构。
