The absolute stereostructures of cicutoxin (1) and related toxic polyacetylenic alcohols, isocicutoxin (2), and virols A (3) and C (4), from Cicuta virosa were determined on the basis of spectroscopic analysis. The CD exciton chirality method was successfully applied to 4-methoxybenzoates of diyne-conjugated polyenyl alcohol systems. Fatal doses of these compounds on mice are also reported.
在光谱分析的基础上,确定了古草毒素(1)和相关有毒的聚乙炔醇,异古草毒素(2)以及病毒C(Cusuta virosa)的病毒A(3)和C(4)的绝对立体结构。CD激子手性方法已成功应用于二炔共轭多烯醇体系的4-甲氧基苯甲酸酯。还报道了这些化合物对小鼠的致命剂量。
