C17-polyacetylenic alcohols of the toxic plant, Cicuta virosa, virols A (1), B (2), and C (3) were synthesized by stereoselective routes to confirm their stereochemistry and to obtain supply of these compounds for pharmacological study. The syntheses used chiral 3-hydroxy-1-alkyne building blocks, Pd(0)-CuI(I)-catalyzed coupling of acetylene with vinyl chloride, and heterocoupling reaction of acetylene mediated
在我们对有毒植物Cicuta virosa的神经毒性C 17-聚炔醇的研究过程中,通过立体选择路线合成了病毒A(1),B(2)和C(3),以确认其立体化学并获得供应。这些化合物用于药理研究。合成使用手性3-羟基-1-炔烃结构单元,Pd(0)-CuI(I)催化的乙炔与氯乙烯的偶联以及CuI介导的乙炔的异偶联反应。结果,确认病毒A(1),B(2)和C(3)的立体定位中心的绝对构型为S,S和小号,分别。
