tetrahydroquinolines based upon reaction of aromatic amines and formaldehyde with electron rich alkenes such as styrene, α-methylstyrene, 1-phenylcyclohexene and 3,4-dihydro-2H-pyran. The isolation of alcohols as additional products from reactions conducted in acetonitrile containing trifluoroacetic acid, and the demonstration that these alcohols reacted further under similar reaction conditions to give efficiently
基于芳族胺和甲醛与富含电子的烯烃(例如苯乙烯,α-甲基苯乙烯,1-苯基环己烯和3,4-二氢-2H-吡喃)的反应,已经建立了四氢喹啉的一锅合成法。从在含三氟乙酸的乙腈中进行的反应中分离出醇作为其他产物,并证明这些醇在相似的反应条件下进一步反应以生成有效的环化产物,这表明本文报道的环化反应不协调。讨论了类似的多步法在将富电子烯烃催化加成到预形成的亚胺中的重要性。
