6‐k]‐5,6,6a,7‐tetrahydro‐4H‐ dibenzo[de,g]quinolin‐10‐one and 1,11‐dimethoxy‐2‐hydroxy‐6‐methyl‐9‐phenyloxazolo[4,5‐k]‐5,6,6a,7‐tetrahydro‐4H‐dibenzo[de,g]quinoline were prepared starting from the alkaloid boldine. The structures were confirmed and the 1H and 13C NMR spectra were completely assigned using a combination of one‐ and two‐dimensional NMR techniques. Copyright © 2001 John Wiley & Sons, Ltd.
新型杂环 1,11-二甲氧基-2-羟基-6-甲基恶唑并[4,5-k]-5,6,6a,7-四氢-4H-二苯并[de,g]喹啉、1,12-二甲氧基- 2-羟基-6-甲基-9-苯基-10H-恶嗪[5,6-k]-5,6,6a,7-四氢-4H-二苯并[de,g]喹啉-10-one和1,11 -二甲氧基-2-羟基-6-甲基-9-苯基恶唑并[4,5-k]-5,6,6a,7-四氢-4H-二苯并[de,g]喹啉以生物碱胆碱为原料制备。使用一维和二维核磁共振技术的组合确认了结构,并完全确定了 1H 和 13C 核磁共振谱。版权所有 © 2001 John Wiley & Sons, Ltd.
