immature seeds of Colchicum autumnale were optimized, so that incorporation rates in the range of 10% and higher were consistently obtained with intermediate precursors. Application of tritium and 13 C-labelled phenethylisoquinolines showed that N -methylation occurs prior to the substitution of ring C and that the free hydroxy group in position 13 of autumnaline is necessary for the phenolic coupling
摘要 优化了秋
水仙未成熟种子应用实验的生理参数,使中间体前体的掺入率始终保持在10%以上。氚和 13 C 标记的苯乙基
异喹啉的应用表明 N-甲基化发生在环 C 取代之前,并且秋天碱的 13 位游离羟基是
酚类偶联反应所必需的。Autumnaline 在这种植物的种子中产生了大量的代谢物。© 1997 Elsevier Science Ltd. 出版。保留所有权利
