dc.description.abstract本文分別探討路易士酸(Lewis Acids)輔佐含氮烯炔醇化合物及布忍斯特酸(Brønsted Acids)輔佐含氮炔醛化合物,進行分子內環化反應。本文主要分三部份進行探討:第一部份以三氯化鐵作為路易士酸和氯離子來源,輔佐第三丁基二甲基矽保護的2-(3-芳香基丙炔基甲苯磺醯胺基)甲基環己-2-烯-1-醇化合物,在室溫,空氣下,進行分子內環化,合成含氯八氫異喹啉衍生物。第二部份則以三氟化硼為路易士酸、乙腈為溶劑,進行第三丁基二甲基矽保護之2-(3-芳香基丙炔基甲苯磺醯胺基)甲基環己-2-烯-1-醇化合物環化反應,在室溫,空氣下,合成八氫異喹啉為主架構之醯胺衍生物。第三部份以布忍斯特酸(雙三氟甲基磺醯亞胺)輔佐1-(3-芳香基丙炔基)-2-甲醛-吡咯啶化合物,於高溫,氮氣下,經炔-醛置換反應(Alkyne-Aldehyde Metathesis),生成四氫-1H-吡衍生物。此四氫-1H-吡衍生物於空氣下,逐漸氧化成具芳香性的二氫-1H-吡衍生物。zh_TW
dc.description.abstractThis thesis focuses on acid-promoted intramolecular cyclization of N-containing O-silyl-protected enynols and N-containing ynals. Three major reactions are discussed. First, FeCl3-promoted cyclization of O-silyl-protected 2-(3-arylpropargyltosylamino)methylcyclohex-2-en-1-ols in the air at room temperature produced isoquinoline derivatives containing an aryl(chloro)methylene moiety. In this process, FeCl3 acts as both the activating group and the chloride source. Second, BF3-promoted intramolecular cyclization of O-silyl-protected 2-(3-arylpropargyltosylamino)methylcyclohex- 2-en-1-ols in CH3CN at room temperature in the air provided octahydroisoquinolines having an amide moiety. Third, NHTf2-assisted alkyne-aldehyde metathesis of 1-(3-phenylprop-2-yn-1-yl)-2-formyl- pyrrolidine afforded tetrahydropyrrolizines at 80 ℃ under an atmosphere of nitrogen. The 2,3,5,7a-tetrahydro-1H-pyrrolizines gradually aromatized to 2,3-dihydro-1H-pyrrolizines in the air at ambient temperature.en_US
