From 1-methyl-6,7-dimethoxy-3,4-dihydroisoquinoline with methyl or ethyl acrylate or with acrylonitrile, via Michael addition products, cis- and trans-1-(3′-substituted-propyl)benzo[a]quinolizidinones and quinolizidines were prepared. The relative configurations and the predominant conformations were determined by means of 1H and 13C NMR spectroscopy, with the application of DR, DNOE and 2D HSC measurements
由1-甲基-6,7-二甲氧基-3,4-二氢异喹啉与丙烯酸甲酯或丙烯酸乙酯或与丙烯腈经迈克尔加成产物,形成顺式和反式-1-(3'-取代-丙基)苯并[a]喹喔啉酮制备了喹喔啉类药物。借助DR,DNOE和2D HSC测量,通过1 H和13 C NMR光谱测定相对构型和主要构象。
