Alkaloids of Corydalis incisa PERS. V. The structures of corydalispirone and corydalisol.
摘要:
从深切紫堇 PERS 中分离出两种新的生物碱,紫堇螺酮,C20H17O6N,熔点 196-198°,[α] D 0°,和紫堇醇,C20H21O5N,熔点 160-161°,[α] D +21.4°。 (罂粟科)。经光谱分析及与荷包牡丹二醇、阿杜脒二醇的化学关联,确定紫堇螺酮的结构为I,经转化为d-四氢黄连碱,确定紫堇醇的结构为VIII。紫堇螺酮和紫堇醇被认为是在苄基部分多一个碳原子的一系列新的异喹啉型生物碱,并且可能是黄连碱的代谢产物。

Tetrahydroprotoberbine (THPB) compounds and their use in the treatment of neurological, psychiatric and neurodegenerative diseases is provided. The compounds include d-govadine, l-govadine and racemic govadine, as well as d-THPBs of general formula (I). Enantioselective processes for preparing compounds of formula (I), and d- and l-govadine are also provided.(I)
A fully continuous flow approachtowards asymmetric total synthesis of four natural tetrahydroprotoberberine alkaloids, was developed through a concise linear sequence involving four chemical transformations and three on-line work-up processes without any intermediate purification. The overall yields and enantioselectivities obtained in this novel integrated flow platform were up to 50 % and 92 %ee
