合成了N(l)-去甲毒扁豆碱的(-)-系列新型氨基甲酸酯。 丁基和辛基类似物都被发现是非常有效的, 体外抑制胆碱酯酶。由(+)-毒扁豆碱合成(+)-毒扁豆碱 完成毒扁豆碱合成的中间体。合成 通过相转移诱导手性的光学活性材料已经 办妥了一批天然N(8)-去甲毒扁豆碱的合成 5-甲氧基-N-甲基色胺已启动,并导致 (+)-N(8)-去甲利血罗啉甲醚。苯乙基脲拆分 方法是有计划的。
英文摘要
Novel carbamates of N(l)-norphysostigmine of the (-)-series were prepared. Both, the butyl- and the octyl-analog were found to be highly potent in vitro in inhibiting cholinesterases. Synthesis of (+)physovenine from intermediates of the physostigmine synthesis was accomplished. Synthesis of optically active material by phase-transfer induced chirality has been achieved. Synthesis of natural N(8)norphysostigmine from 5-methoxy-N-methyltryptamine has been initiated and led to (+)-N(8)-noreseroline methyl ether. Resolution by the phenylethylurea method is planned.
